摘要(Abstract)：

用SEM和XRD观察和分析了铝含量和合金化时间不同的热镀锌合金化(GA)镀层的表面形貌和组织,用双杯突测量了GA镀层的抗粉化量。结果表明,锌液中铝含量小于0.16 mass%的热镀锌镀层合金化时,镀层表面的Ra值小于1.0μm,且镀层的粉化量小于30 mg/m2,满足汽车板的表面质量要求;此后随着锌液中铝含量的增加,GA镀层的粉化量迅速增加,说明GA镀层的抗粉化性能除与镀层中的铁含量有关外,还与镀层表面的粗糙度有关。锌液中铝含量为0.22 mass%热镀锌镀层合金化时,由于Fe2Al5Znx抑制层的抑制作用,镀层中的δ1k-相出现局部增多的现象,从而恶化了GA镀层的抗粉化性能。
