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.

NASF/AESF University Funded Research Transitioned to Industry: Practical Performance Improvements in Functional REACH-Compliant Trivalent Chromium Plating

This paper shows information learned from a NASF/AESF Foundation Research grant which has led to successful application. The work at the University of Houston (UH) is discussed – a technique developed to perform in-situ analysis of the stress of the chromium deposit from a REACH-compliant trivalent chromium electrolyte. An understanding of crack formation during plating has led the way to a means to avoid it. Faraday Technology Inc. scaled-up and optimized the same process through support from the U.S. Army. The results enabled significant chromium coating performance enhancements, matching the wear index of conventional Cr deposits from hexavalent baths.

Dr. Phil To The Rescue for Electroplaters

Techmetals’ president Phil Brockman is often the last electroplater that some customers visit on their search for solutions to persistent finishing issues or to plate unique parts. But it’s easy to see why most major aerospace, medical, defense, oil/gas, mold shops, and automotive manufacturers end up at Techmetals’ expansive facilities in Dayton, Ohio.
