Metals are separated based on boiling point differences, ensuring strict discharge limits are safely met. Potential combined treatment of alkaline and acidic rinsing water from pickling-degreasing and anodizing enables reduced investment and operating costs. Downstream evaporation enables reducing residual water content in evaporation residue, lowering disposal costs, and potential secondary raw materials recovery.

11:10 a.m. - 11:55 a.m.: Towards Cr(VI)-Free Anodizing of Aerospace Aluminum Alloys for Metal-to-Metal Bonding; Prof. Arjan Mol, Delft University of Technology, Dept. of Materials Science and Engineering; Classic aluminum pre-treatment for metal-to-metal bonding of aerospace structures applies chromic acid anodizing to generate porous anodic oxide with optimal strength and adhesion using carcinogenic hexavalent chromium (Cr(VI)). To identify comparable Cr(VI)-free candidates, the relation between oxide properties and interfacial bonding under dry, wet, and corrosive conditions is studied under changing parameters. Characteristics critical for bonding, oxide chemistry and morphology are highlighted. Cr(VI)-free anodizing electrolytes and porous oxide morphology are explored. Results show chemical and morphological surface properties are critical considerations when selecting Cr(VI)-free alternatives for structural adhesive bonding.

12:00 p.m. - 1:00 p.m.: Lunch

1:10 p.m. - 2:00 p.m.: Automation: Technology Solutions that Regenerate Operations; Tamea Franco, Global Metal Finishing; After unforeseen acquisition of a software operating system, the barriers and rewards are presented when the Global Metal Finishing team navigated the challenges of finding, quoting and operating software and hardware that complied with ITAR and enforced cyber security. Customer engagement, systems improvements, and overall gains are highlighted. Whether a captive shop or job shop, aluminum anodizers must satisfy customer requirements at lightning speed, often with inadequate information and unrealistic expectations. Anodizers are demonstrated to be the Heroes in the supply chain, bringing on-time technical and profitable solutions to customers’ internal dysfunctions.

1:10 p.m. - 2:00 p.m.: Anodizing Fundamentals: Risk Elimination System: The Road to Zero Injuries; Dawn Purucker, Bonnell Aluminum; Leading Key Performance Indicators can reliably predict where injuries will occur before they happen, driving safety culture toward a future where fewer hazards are present. The Risk Elimination System, an associate-based approach to removing hazards, enables shop-floor associates to make decisions about their work environment. When utilized as a tool to address potential problems, associates can reliably prevent incidents from occurring. A proactive approach to site safety while focusing on sustainable individual contributions has consistently reduced overall injuries with the lowest TRIR in Bonnell Aluminum’s history.

1:10 p.m. - 2:00 p.m.: Technical: Heavy Metal Free Dyes; Mahe Chandrasekaran, Techevon, LLC; This presentation describes the introduction of metallizing dyes and the benefits of such metallizing. Different metals that can be used when metallizing and the advantages and disadvantages of each metal are reviewed. These options will be demonstrated specific to the dyes that are suitable for anodizing. There will be an emphasis on replacing Chrome with more eco-friendly metals or in the best case, the development and benefits of non-metallized dyes. All of these choices are performance tested using the criteria of contamination and light fastness.

2:10 p.m. - 3:00 p.m.: Automation: Automated Racking and Other Modernization; Petter Isaksson, Ahlins; The Job Shop anodizing business must step up to modern ways of production. Digitalization, Industry 4.0, the Internet of Things (IOT) and other buzzwords surround us all the time. In what aspects are they influential to our small operation? What has been accomplished by Ahlins in these areas will be highlighted and discussed regarding automation in different applications, from picking parts to more complex systems.

2:10 p.m. - 3:00 p.m.: Anodizing Fundamentals: The 720 Rule: Anodized Aluminum Coating Thickness Variation in Some Aluminum Alloys; Dr. George N. Oh, Quaker Houghton; The industry-standard 720 Rule determines operational parameters during aluminum anodization to obtain desired coating thickness. Though useful for many aluminum alloys, this fails for alloys where non-aluminum constituents comprise a relatively large portion of the metal. AA5005, AA6063, AA6061, and AA7075 are anodized at constant current using the 720 Rule, and differences in actual obtained thicknesses are determined. Differences in thickness are also reported when anodizing at constant voltage under the same conditions. Results point to the importance of monitoring and segregating alloys when anodizing.

2:10 p.m. - 3:00 p.m.: Technical: Using Surface Analytics for Monitoring Aluminum Finishing Processes; Michael Valenti, Hubbard-Hall; Traditional methods for maintaining process control of aluminum finishing lines, such as chemical titration, conductivity measurements, pH and others, have limitations, and don’t always give a complete picture of part quality. In this session, we will discuss using surface analytics as a tool, to improve predictability of quality, cleanliness, and other critical surface properties of aluminum moving through the process. The discussion will focus on how a proven surface science can be deployed with better technology for the manufacturing environment.

Interfacial interactions between Porous Anodic Oxide and organic coatings mainly determine organic/inorganic system durability. Model interfacial interactions of polymeric films on modified aluminum oxides are presented, using in-situ analytical methods to characterize a realistic model interface exposed to the environment. Interfacial interactions when water vapor is present are described. Local deposition of organic molecules is probed; anodic film degradation is investigated using corrosion and adhesion tests, combining anodic films with chromate-free and chromate-loaded model primers.

4:10 p.m. - 5:00 p.m.: Automation: Spray Dyeing of Anodized Aluminum with Organic Dyes; Britta Dickmeiss, Bang and Olufsen; For the last 24 years, Bang and Olufsen has been using a spraying technique when coloring anodized aluminum. Spray dyeing has many advantages over the normal dipping process such as increased flexibility, which is important in order to meet the demands from our designers. Both the pros and cons of using the spraying technique will be discussed, together with some of the challenges that have been experienced when trying to make the same shades by a dipping process.

4:10 p.m. - 5:00 p.m.: Anodizing Fundamentals: How to Ensure Lightfastness of Type II Dyed Anodized Aluminum; Jacqueline Cook, Reliant Aluminum Products; Ensuring lightfastness for dyed anodized aluminum to an architectural level is challenging. Picking the correct dye with an architectural-grade lightfastness rating is the first step to ensure dyeing that withstands years of exposure. Coating thickness, weight, density, dye concentration and activity, seal quality and chemistry all play vital roles in creating a good UV-resistant coating. Various factors are presented highlighting dyes and their management to retain a quality part. This presentation provides insights into managing the line for maximum efficacy with cost and environmental factors in mind.

4:10 p.m. - 5:00 p.m.: Technical: Addressing the Demand for Clear Cr (III) Chemistries for Passivating Aluminum Alloys; Jacob Weingart, PhD, Columbia Chemical Company; Understanding and enhancing aluminum alloy corrosion resistance is widely studied to maintain key mechanical properties and aesthetic appearance for industrial and consumer applications. Surface treatments are examined that impart protective inorganic layers to help mitigate atmospheric corrosion. Focus is on the demand for, and development of, trivalent passivates to address growing environmental, regulatory and health concerns of hexavalent chromates. A clear aluminum trivalent passivate is reviewed that achieves excellent corrosion protection and enhanced durability, evaluating performance factors including appearance, operating range, and salt spray analysis.
