在工件表面制备ZnAlZr多元合金防腐涂层的方法
摘要：
本发明提供一种在工件表面制备防腐涂层的方法，包括：提供包括以下重量百分比的共渗剂粉末：15wt％～30wt％的锌粉、10wt％～20wt％的铝粉、10wt％～20wt％的锆粉、0.1wt％～2.0wt％的活化剂粉、余量的填充剂；将工件包埋在所述共渗剂粉末中加热至400℃～500℃，保温3小时～10小时进行共渗处理。与现有技术相比，本发明通过共渗剂粉末中添加了一部分锆，并改变了共渗剂中其它成分的含量，实验结果表明，防腐涂层增加锆元素后，防腐涂层的抗腐蚀性能和表面硬度均得到了明显的改善。
摘要（英）：

The invention provides a method for preparing an anticorrosive coating on a workpiece surface. The method comprises the following steps: providing the following co-doping agent powder by weight percent: 15wt%-30wt% of zinc powder, 10wt%-20wt% of aluminium powder, 10wt%-20wt% of zirconium powder, 0.1wt%-2.0wt% of activating agent powder and the balance filling agent; and embedding and heating a workpiece in the co-doping agent powder to 400-500 DEG C, and performing heat preservation for 3-10h for co-doping treatment. Compared with the prior art, one part of zirconium is added into the co-doping agent powder to change the content of other components in the co-doping agent; and the experimental result proves that the zirconium element is added into the anticorrosive coating to obviously improve corrosion resistance and surface hardness of the anticorrosive coating.
