硫酸铝钾饱和水溶液(简称明矾)试剂作为不锈钢组织的电解浸蚀剂,效果很好。本文是应用明矾试剂作电解浸蚀的举例介绍。一、奥氏体不锈钢组织的显示: 如对1Cr18Ni9Ti钢和0Cr18Ni9Ti钢(晶粒≥4.0级)能完整地显示出晶界孪晶和滑移线(图1)。
Potassium aluminum sulfate saturated aqueous solution (referred to as alum) reagents as stainless steel electrolytic etching agent, the effect is very good. This article is an example of the use of alum for electrolytic etching. First, the austenitic stainless steel shows: such as 1Cr18Ni9Ti steel and 0Cr18Ni9Ti steel (grain ≥ 4.0 grade) can completely show the grain boundary twins and slip line (Figure 1).
