PURPOSE:To form a zinc layer with high adhesive strength on the surface of a low alloy steel strip by zincification by activating the surface of the strip by dry etching and by zincifying the activated surface by vacuum deposition. CONSTITUTION:The surface of a low-alloy steel strip contg. highly oxidizable metallic elements such as Si, Cr, Mo and Mn is dry etched by plasma etching or other method to remove the oxides of said highly oxidizable elements formed on the surface during annealing. The surface of the strip activated by the etching is zincified by vacuum deposition. A zinc layer with high dhesive strength is formed on the surface of the low alloy steel strip by the zincification. |
