摘　　要：针对镀锌汽车外板冲压掉锌问题,以来自不同厂家的冲压成型过程中掉锌表现差异较大的3种镀锌板为研究对象,对比了它们的锌层结合力、微观形貌、显微硬度和摩擦因数。结果表明,在锌层结合力良好的前提下,锌层的均匀性、显微硬度和摩擦因数对镀锌板冲压成型掉锌有较大影响。As for the peeling of zinc coating appearing during stamping of automotive zinc-coated outer plate,the adhesion,micromorphology,microhardness,and adhesion of zinc coating on three kinds of automotive zinc-coated outer plates from different manufacturers,which differed greatly in peeling degree during stamping.The results showed that the uniformity,microhardness,and friction coefficient of zinc coating had great impact on peeling of it during stamping under the premise that the zinc coating had good adhesion to the substrate.
