酸洗产品“小黑点”缺陷显微分析

Analysis of ’small black spot’ defect on the pickled strip surface

某厂生产的酸洗产品表面存在＂小黑点＂缺陷,严重影响了产品的表面质量,影响下道工序的生产使用。针对该缺陷介绍一种便携式显微镜分析方法,并采用扫描电镜对显微分析方法的结论进行了确认。

Aimed at the＇small black spot＇defect occurring on the pickled strip surface,which seriously impacted the surface quality of the products and the production condition of next process,aportable microscopy was used to test this defect.The test results were verified by scanning electron microscopy（SEM）.
