绪言金相電解磨光法早在1925年就被發現了,但一直到1935年以後才有較大的發展,並實際應用於金相試片的製备,後來更推廣應用於工業上。電解磨光的整个作用過程目前尚未充分明瞭,一般解释為:將金屬或合金試片作為陽極,置於一能溶解該金屬或合金的溶液(溶液的種類 INTRODUCTION The metallographic electrolytic polishing method was discovered as early as 1925, but it has not been developed until after 1935, and has been actually applied to the preparation of metallographic specimens. Later, it was more widely used in industry. Electrolytic polishing the entire role of the process is not yet fully understood, the general explanation is: the metal or alloy specimen as the anode, placed in a solution to dissolve the metal or alloy (the type of solution
