Abstract
- Abstract: Chromium–palladium alloy films with good adhesive strength and higher micro-hardness have been deposited on 316L stainless steel by pulse electroplating. The films are composed mainly of chromium and palladium crystallites in the metallic state, with grain sizes less than 100nm. On the film surface Cr(OH)3 and Cr2O3 are present. The co-deposited Cr and Pd in the films show a synergetic effect on passivation. In boiling 20wt.% H2SO4 solution, boiling acetic–formic acid mixture, and simulated PEM fuel cells environment, the Cr–Pd-plated 316L steel shows excellent corrosion resistance.
