摘　　要：基于电镀锌镍钢板脱锌前后的力学性能试验及拉伸试验过程中镀层表面的微观变化 。In this paper,the influnces of ZnNi coat on r value and n value are investigated by tensile test.The microcosmic changes are also observed during tensile procedure.Then the main cause of decreasing coefficient of normal r value and workhardening exponent n value is given.
