电位法判定Ag-Ni复合材料的金相浸蚀

Metallographic Etching of Ag-Ni Composite by Controlled Potential

Ag—Ni复合材料的金相浸蚀不同于单独银和镍的浸蚀,其浸蚀行为发生了一些变化。用分别测定银、镍在浸蚀剂中的电极电位的方法,选择了适合的浸蚀剂及其浸蚀方法。

The metallographic etching process for Ag-Ni composite was different from the divisible etching processes for nickel or silver because of the variation of etching behaviours. A proper etching reagent was choiced by the determination of electrode potentials in this etching agent respectively. The etching behaviours and their etching process were explained theoritically.
