摘　　要：采用循环伏安法研究了弱酸性氯化钠型锌－钻合金电沉积机理，扫描电镜及X－射线衍射实验说明由于钻的存在影响合金镀层的表面结构，晶型相同但择优取向发生了改变。The electrodeposition behavior of Zn - Co alloy obtained from weakly acidic sodium chloride electrolyte was studied by means of cyclic vlotammetry .Scanning electron microscopy and X- ray diffraction experiments show that the presene of a small amount of cobalt in the deposit influences the crystal structure and changes the preferential direction of crystal growth.
