Developing Standardized Testing for Trivalent Chromium Thickness: A Progress Report
The industry shift toward trivalent decorative chromium plating and away from hexavalent highlights a need for testing standards. As Chair for ASTM B08.10 Subcommittee on Test Methods for Metallic and Inorganic Coating, Mark Schario is leading the committee’s focus on developing standardized testing for trivalent chrome thickness. This presentation provides information on the initiative, testing methods and variables, initial data on thickness comparison and alloy composition, and summary of input and extended lab testing.

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.
