Description

A kind of electro-etching device

Technical field

The utility model belongs to electrolytic etching technique field, is specifically related to a kind of electro-etching device.

Background technology

Etch method is that metallographic structure shows a kind of common method, the method utilizes metallographic specimen respectively to organize the difference of physicochemical property between constituent, make its surface produce selectivity etch, now the microfluctuation of specimen surface is corresponding with its interior tissue, thus demonstrates tissue signature.Etch method is divided into chemical etching and electro-etching two kinds, the metal very high for corrosion stability and alloy are as the noble metal such as platinum, gold, silver and alloy thereof, and stainless steel, nickel base superalloy, high-alloy steel, titanium alloy, wimet etc., because its chemical stability is high, be difficult to show its tissue with chemical etching method, often adopt electro-etching method.Electro-etching normally samples on high resistance to corrosion hardware to be measured, and sample, after the operations such as polishing, polishing, adopts electro-etching method to corrode sample flour milling, to show its metallographic structure.Can only carry out etch to one to two sample in the at present conventional electro-etching device same time, efficiency is low, etching solution injures large defect to operating personnel treating to have in the more situation of etch sample.
