Electrically mediated process for functional trivalent chromium to replace hexavalent chromium: Scale-up for manufacturing insertion

This project work is investigating the various parameters affecting the plating of chromium from a trivalent chromium bath. Since the project is still active, this is an update on accomplishments to date involving the bath chemistry, diffusion layer and electrically mediated waveform parameters. This paper will report on the progress toward establishing a pilot-scale electroplating line for both shock absorber rods and pump augers. The pilot-scale line is a complete system, including waste management protocol relating to both air and effluent waste management considerations. The project is being funded by the U.S. EPA and a commercial partner.
