Anotation

This guide outlines the standard procedure for establishing and maintaining a preparatory cycle for electroplating on high carbon steel producing minimal hydrogen embrittlement and maximal adhesion of the electrodeposited metal. The reagents needed for this method are technical grade hydrochloric acid, nitric acid, sulfuric acid, and water. Steel substrates shall conform to required hardness, hydrogen embrittlement, and surface oxidation characteristics, and quality. Proper preplating treatments such as precleaning, stress relief treatment, mechanical treatment, electrolytic anodic cleaning, hydrochloric acid treatment, treatment for smut removal, anodic acid etching, and electropolishing shall be performed. Coating adhesion and embrittlement shall be tested.
