Improving the Wear Performance of Functional Trivalent Chromium Plating Via Pulse-Reverse Electrodeposition

This paper covers work on improving the wear performance of a functional chromium coating from a trivalent chromium plating bath. Wear resistance is a critical aspect of chromium coatings when used in components of both ground-based and aerospace vehicle systems. Traditional hexavalent chromium coatings have shown exceptional wear resistance in these applications, while the wear resistance of trivalent chromium coatings has been less satisfactory. Using pulse-reverse electrodeposition to control various characteristics of the chromium coating, the wear performance of trivalent chromium plated panels could be improved. A multivariate regression model of the electrodeposition conditions shows that bath chemistry parameters within the range of viable plating are not a large contributor to the variance in wear performance, while the roughness and size of macro-cracks is very important for wear-related applications. The multivariate analysis approach undertaken in this study may find potential applications in broad areas of the plating and finishing industry.

Modeling and Simulation for the Finishing Industry - the 55th William Blum Memorial Lecture

As Dr. Keith Legg, 2019 recipient of the NASF Scientific Achievement Award, watched the changes in industry over the past decade or so, he has seen modeling and simulation move from one industry to another. Seeing how and where it is used elsewhere, he concludes that modeling could be more widely and profitably used in the surface finishing industry. In his Blum lecture, he discusses how modeling for surface finishing is a recognized approach today. It is proving to be very useful for plating and some finishing processes and is finding new uses as it develops, but there is a lot to learn. The aim is to make modeling a standard, integrated approach to coating development and corrosion protection.
