摘　　要：采用体视显微镜观察了机械镀锌镀层及锌球和玻璃珠介质的表面形貌,采用ICP–AES和XRD分析了所产生锌球的化学成分及物相组成,并给出了预防锌球产生的措施。结果表明,锌球由锌、锡、铁3种单质构成,其产生原因是冲击介质表面存在较多的凹坑或麻点,或镀桶内添加的Sn2+过量。The surface morphology of mechanical zinc plating deposit, zinc balls and glass beads media were observed by stereomicroscope. The chemical and phase compositions of the zinc ball were analyzed by X-ray diffraction （XRD） and inductively coupled plasma atomic emission spectrometry （ICP-AES）, and the measures to prevent zinc ball production were suggested. The results showed that the zinc ball is composed of three simple substance of zinc, tin and iron, and the reason for it＇s production is the existence of more pits and pockmarks on the surface of impact media, or excessive tin（Ⅱ）,ion addition in plating barrel.
