PRINCIPLES OF METALLOGRAPHIC ETCHING.

Abstract

The principles of metallographic etching have been determined by electrochemical and optical measurements on tin-zinc alloys in sodium hydroxide electrolytes. The minimum dissolution rate ratio and the minimum amount of selective dissolution necessary to achieve metallographic contrast of phases have been measured. Etching rate and contrast are uniquely defined by etching potential by potentiostatic, electrolytic and chemical etching methods. (Author
