2.4. Mechanical, Chemical, and Electrochemical Surface Treatment Prior to Electroplating Mechanical

ABSTRACT

Mechanical surface treatments such as cold drawing, grinding, and polishing have a tendency to increase the susceptibility to embrittlement. These effects can be relieved by retempering within 50°F of the original tempering temperature or by anodic etching to remove the stressed surfaces.
