利用扫描电镜(SEM)、能谱(EDS)和X射线光电子能谱(XPS)仪对合金化热镀锌(GA)板漏镀缺陷进行了分析。结果表明,导致漏镀的主要原因是带钢表面碳沉积,氧化锌粘附以及表面残留有轧制油。
Leakage defects of the alloyed hot-dip galvanized (GA) sheets were analyzed by SEM, EDS and XPS. The results show that the main reasons lead to leakage plating is carbon deposition on the strip surface, zinc oxide adhesion and residual oil on the surface.
