Electro Chemical Machining (ECM) Surface Characteristics

摘要

The electro chemical machining (ECM) process is one that dissolves metal into a hydroxide form as metal is removed from a part. The resultant is a stress free etched surface. This presentation examines the characteristics of the surface left by the ECM process. It will examine the quality of the surface finish along with the metallurgical effects on the workpiece. Intergranular attack and fatigue effects will be discussed.
