Corrosion Resistance of Titanium Palladized by Electro-Sparking with Subsequent Anodic Plasma-Heating in Aqueous Electrolyte

摘要

The effect of anodic beating in electrolytic plasma (AHEP) on the corrosion and electrochemical behavior of titanium with electro-spark palladium coatings in 10-40 percent H_2SO_4 solutions at 100 deg C is studied. It is shown that the treatment by the AHEP method enhances the corrosion resistance of palladized titanium by more than one exponent. This is due to the formation of palladium-containing oxide-carbide layers.
