Cathodic Alloying of the Surface of Titanium, Chromium, and Stainless Steels as a Method of Increasing Their Passivation and Corrosion Resistance Available to Purchase

The electrospark technique and electrochemical deposition from solution followed by annealing were used to alloy the surface of titanium, chromium, and stainless steel with electropositive metals. It was found that surface alloying was an effective substitute for volume additions. It was found that alloying the surfaces of titanium, chromium, and stainless steels with Pd substantially improved their corrosion resistance to sulfuric and hydrochloric acids.
