摘　　要：主要通过观察试验,并借助于扫描电子显微镜,结合物理化学、电化学的基础理论知识,对机械镀锌合金化过程中先导金属的作用机理进行了研究。从金属粉的合金化、铁基表面的合金化、镀层的合金化及枝晶生长理论4个方面分析了先导金属对机械镀锌合金化过程的影响。结果表明,机械镀锌合金化过程中先导金属的确起着非常重要的作用,而且先导金属可以促进机械镀锌镀层的结合强度,可以用先导金属的作用机理解释机械镀A、lZn时的各个过程。The driving metal mechanism in mechanically deposited alloy process is studied by SEM, tridimensional microscope on the base of physical chemistry and electrochemistry. The influences of driving metal on mechanical plating alloying are analyzed from four aspects, they are alloying of metal-powder, alloying of iron surface, alloying of coating and growth theory of arborescentcrystal. The results show that the driving metal really has very important function in the process, and driving metal can enhance binding intensity, and its action mechanism can interpret any process of mechanically aluminium and zinc deposited.
