Abstract

Process comprises immersing steel in a reduced chromic mixt. bath, contg. a sulphuric/chromic soln. at near the b.pt. of water. To increase efficiency, the steel is cleaned prior to immersion. - The remainder of the soln. is removed by thorough washing with water, prior to final anodic electrochemical attack in a different reduced chromic soln..
