    Recent Developments of Colored Anodic Films for Space Applications
    The preparation of environmentally friendly and efficient coatings on metal and composite parts is one of the main challenges of surface treatments for space applications. In this context, CIRIMAT developed new processes to prepare innovating anodic films, as alternatives to the usual coloring process. Professor Arurault will talk about how various tests (thermal cyclings and UV tests) were performed in order to evaluate their resistance to a simulated space environment. Details of the results showing that these alternative processes succeeded in preparing new coatings showing the required thermo-optical properties (solar absorption and emittance) will be addressed. In addition, terms of resistance to the space environment, showed promising results but some disparities were observed and then discussed according to the coloring process used.

    Thin Substrates of Anodic Porous Alumina for Living Cells Sensing
    We have investigated the feasibility of thin anodic porous alumina (APA) films as a surface for the development of analytical biosensors aiming to assess the status/functionality of living cells. The APA template covered with Au acts both as cell seeding surface and as a convenient Surface Enhanced Raman Spectroscopy (SERS) substrate.
    Thin films of Al (~ 500 nm) evaporated on glass were anodized at 110 V in 0.3 M H3PO4 solutions, yielding thin APA with pores with ~ 50 nm diameter, reaching ~ 150 nm after post fabrication etching. Thin APA with long-range uniformity and a good reproducibility was obtained.
    Biocompatibility tests using neuroblastoma cells were performed to assess cell viability, adhesion and proliferation on thin APA.
    Surface Enhanced Raman Spectroscopy (SERS) investigations performed on selected test molecules adsorbed on thin Au-coated APA revealed a good enhancement of the Raman signals from the molecular probes. Finally, SERS measurements on the living cells in liquid buffer were performed, yielding Raman spectra with sharp peaks attributed to the different components of the cells, without need of an external label.

    Aluminum and the Road to 54.5 Implications for Anodizers
    With Ford’s launch of the 2015 F-150 early this year, the general public caught on to the fact that those in the aluminum world have known for several years – that aluminum will play a major role in the automakers’ plans to greatly improve fuel efficiency and reduce their carbon footprint.

    This session with look at the accelerating use for aluminum in North American autos, the issues yet to be resolved, and the implications of this market development for anodizers. We’ll also take note of the emerging response by competitive materials.

    Team Building and Employee Engagement
    Information on how to build productive teams in a manufacturing environment will be addressed. Employee engagement is one of the critical elements to the success of working as a team. The discussion will include ideas on how to help get employees engaged in the specific goals of their department as well as their company as a whole. Statistics, in terms of the percentage of employees who are actively engaged, on the fence, or actively disengaged will be addressed as well as how to work with each group.
    Speaker(s):
    Managerial Accounting for the Anodizing Shop
    Managerial accounting is concerned with providing information for those inside the organization, such as plant managers, line managers and supervisors - for the purposes of planning, controlling, quoting and evaluating performance. A good place to begin in the development of a managerial accounting system is costing the anodize line. Kevin will emphasize starting small and letting the process grow. This session will explain how to cost the anodize line, how direct labor represents the largest cost and yet it receives the least attention and how racking and unracking should be a top priority to develop a good costing system, and several other key areas of importance. The business environment is always changing with demands for higher quality products at lower prices and costs. Today’s anodize plant manager, line manager and supervisor need to have more information at their disposal to better manage their processes and associates. Implementing a managerial accounting approach is a step in providing that information, evaluating the performance of the organization and the effects of modifications within the organization.

    Sales and Marketing of Anodizing Services in the Job Shop
    Marketing anodize services is more than just having a web-site or placing an advertisement in a trade magazine. There are many ways businesses can present themselves to the marketplace and many strategies to consider. Case studies highlighting these methods are presented. This interactive presentation is designed to provoke thought and hopefully enlighten anodizers to decide “who we are” in this highly competitive marketplace.
    Speaker(s):
    Strategies to Grow Demand for Anodizing Finishing
    Generally, aluminum extrusions are supplied mill (unfinished), painted (liquid or powder) or anodized finish, leaving manufacturers and applicators of coatings competing on specifying their products and services. Aluminum extrusions are valued for their light weight, strength, corrosion resistance, low maintenance, finish options and contribution to sustainability; however, with consumers increasingly seeking for durable and long-lasting materials, manufactured with the least impact to the environment, aluminum extruders and processors of commercial products must, once again, align themselves to meet new and more stringent market demand. This session is intended to provide the attendees with possible strategies aimed at growing the demand for anodize finishing in the commercial architectural market.

    1:30 PM  -  2:00 PM
    Review of Current Developments in Recycling
    The aluminum industry faces a number of challenges associated with recycling of both fabricating and post consumer aluminum scrap. Contamination of aluminum scrap streams, either by different aluminum alloys, surface coatings or organics can limit their usage in many applications, due to either the resulting metal quality or issues associated with environmental emissions durign processing. Metal recovery from many scrap streams can also be an issue, as the high surface area to volume ratio of many of these materials can lead to high melt loss during remelting. With the expected impending increase in aluminum usage for automotive applications, there will be an influx of new aluminum fabricating scrap in the short term and in post consumer scrap in the longer term. These issues and potential solutions will be discussed in this review.

    2:15 PM  -  2:45 PM
    Primary and Secondary Alloys – A Performance Comparison
    There has always been a concern about the anodizing and finish response between Primary Aluminum Alloys and Secondary Aluminum Alloys. This session will provide an explanation of the preparation of the two types of alloys, a comparison of their metallurgical properties, their resulting different anodizing responses, with insight on how to manage those responses to produce acceptable anodized finishes.
    Speaker(s):
    3:00 PM  -  3:30 PM
    A New Type of Waste Water Treatment for Zero Discharge: ZDCM (Zero Discharge Chemical Method)
    The innovative patented system is a “revolution” compared to conventional physical chemical systems and has been particularly designed for the treatment of liquid wastes derived from anodizing plants and powder coating pretreatment. In the past it was possible to partially or totally recycle the wastes in aluminium finishing plants, but it was necessary to use expensive equipment like evaporators, expensive as concerns capital investment and running costs.

    Nowadays it is possible to reach zero liquid discharge thanks to a new method that uses active complex chemicals able to eliminate the ions in the waste water and to form a sludge which is more compact than usual (sludge reduction in volume up to 50% ) and creating a non-toxic kind of sludge.

    There are plants in Europe that already operate at an industrial level with this innovative system and we think that the ZDCM (Zero Discharge Chemical Method) will be, in the coming years, one of the most important “technical revolutions” in the aluminium finishing industries and, due to the possibility of cost reduction and the ecological impact on the environment (low or almost zero water consumption and low or even zero discharge), the new ZDCM will make the aluminium finishing companies more competitive and “green”, giving new opportunities and strength to our industries.

    3:45 PM  -  4:15 PM
    Legitimate vs. Sham Recycling for Anodizing Waste Streams
    The aluminum anodizing process often results in the generation of secondary materials that have value and can potentially be recycled or reclaimed instead of disposed of; however, certain environmental regulatory requirements must be met to ensure these materials are truly considered recycled and not waste material. The issue of legitimate versus sham recycling has been a hot topic for USEPA for many years and USEPA has developed a standard defining legitimate recycling. This session will focus on the USEPA regulatory requirements associated with legitimate recycling.

    4:30 PM  -  5:00 PM
    The Legal Pitfalls Involved in Recycling Anodizing Waste Streams
    As a companion to the paper on regulatory aspects of recycling to be presented at this conference, this session will focus on recent federal court cases, including Howmet, that provide insight into EPA’s enforcement process for recycling claims; information about the dangers of relying on a RCRA primacy state’s concurrence regarding recycling, and the long term ramifications of the revised federal definition of Solid Waste on recycling in this industry.

    How to Achieve Uniform Thickness of the Anodic Aluminum Oxide Film
    How to achieve uniform thickness of the anodic aluminum oxide film? DC voltage applied across the tank creates electric field that exists at any point in the electrolyte and in the oxide film. If a positive test charge is placed at that point it would experience an electric force. The direction of the electric field at a point is the same as the direction of the force experienced by a positive test charge placed at the point. Electric field lines can be used to sketch electric field. The line through a point has the same direction as the electric field. Field lines come out of positive electrodes (anodes) because positive electrodes repel a positive test charge. Field lines come to negative electrodes (cathodes) because a negative electrode attracts the positive charge. Where the field lines are closest together, the electric forces are the largest. The electric intensity E (also called the electric field stress) at a point is equal to the force experienced by a unit test charge placed at that point. The electric intensity between anode and cathode having plate configuration is uniform. The electric intensity is equal to drop of voltage V = V anode – V cathode between plates divided by the distance d between plates: E = V/d This picture is valid for electroplating where the tank voltage ordinarily does not exceed 10 VDC. In aluminum anodizing we have four fields with different electric intensity plus non-uniform coating due to: worn out cathodes, too quick ramp, anode / cathode ratio off, too great a load for the tank, high current density, wrong aluminum alloys for racks, poor part distribution in process tank, wrong cross section of racks, different surface finishing on the same part, other obstacles on the surface area, poor metal quality,poor metal storage, poor cleaning with subsequent etching, screening effect, etc.

    Materials Characterization of Anodized Aluminum Using Physical Analytical Methods
    Anodization of aluminum from various alloys has unique challenges with respect to surface cleaning and growth kinetics. Residues from cleaning operations and possible chemical reactions may cause development of surface defects. Similarly, anodization and a subsequent sealing operation often need detailed understanding of the microstructure of the columnar growth of the oxide layer. Methods such as TEM and XPS can provide critical analytical data for defect-free anodization of aluminum.

    1:30 PM  -  2:00 PM
    Appearance of Anodic Coating with Different Mechanical Finishes
    Anodic coatings have the unique characteristics of being true to the media. This means that the finish, unlike organic coatings, has no hiding power which can be used to significantly enhance the appearance and produce a finish that is very attractive. This presentation will review the effect of appearance of anodic finishes using different mechanical treatments. The pros & cons of each of the treatment methods will be discussed and the effect of colors will be shown on each of the effects.

    Effect of Color Changes When Sealing Anodic Coatings in Different Nickel/NonNickel Sealing Processes
    Organically colored anodic coatings have traditionally been sealed in hot nickel based sealing chemistry to minimize color variations. With the desire to reduce or eliminate nickel waste in anodizing plants alternative methods of sealing have been developed but most of these have had limited use in plants because of the color control difficulties associated with sealing in non-nickel based seals. This presentation will show some interesting possibilities of reducing and/or eliminating the nickel from waste streams.

    4:30 PM  -  5:00 PM
    Using Optical Systems for Quality Assessment of Anodized Aluminum Surfaces
    Any optical system used for the surface finish measurement of an ano part needs to recover the signal from the air-ano layer, which is very weak in comparison to the signal on the ano-aluminum layer. Confocal based optical systems work very well for this purpose, but they have the drawback of having to use high numerical aperture objectives, only possible with high magnification, and thus the need to use stitching to recover millimeter scale. This makes the measurement a slow task and not suitable for production environments.

    On the other hand, Coherence Scanning Interferometry (CSI) based systems can evaluate larger areas while keeping good signal separation between both interfaces. Some optical measurement systems can combine both, Confocal and CSI, for the evaluation of surface texture in the aluminum and the oxide layer at the same time. This makes it possible to characterize defects in 3D prior to the anodization process as well as assessing the quality of the final product.
