Anti-Wear Improvement of Stamping Die Materials through Duplex Chroming

A presentation given by Eric McCarty, A/SP Senior Project Manager, at the 2018 Great Designs in Steel. The project was based on the hypothesis that adding a nitride layer between the chrome plating and the substrate die material can improve sliding-impact wear performance by combining the lower friction of the chrome coating with improved load support of the nitride coating. The combination of chrome plating over nitriding is called Duplex Chroming.
