By using SnSO4 water solution to activate global granular Zn powers of 325 screen mesh,Zn-Sn composite coverage is formed under the action of mechanical impact of the tiny glass beads and work pieces.During and after the formation of coating,acid water liquor will react with metal basal body,and hydrogen gas is bound to emit from the pathway and form micro pores.In addition,there are bond areas between the new and the primary coverage,which may lead to the emergence of micro crack on the coating owing to such causes as too big or uneven impact during plating process,little distortion of global granular zinc dust inside the plating coat,less tight coalescent of the zinc dust flecks.
