Technology of obtaining Zinc-based sintered coating with globular Zinc powder was studied. 探索了球狀鋅粉鋅基燒結(jié)涂層的基本工藝條件。
Polytetrafluoroethylene (PTFE) with mass ratio of 10% was added in the coating process of mixed zinc powder to substitute polyvinyl alcohol (PVA) of traditional technology. 在混合鋅粉包覆過程中，添加質(zhì)量比為10％的聚四氟乙烯（PTFE）取代傳統(tǒng)工藝的聚乙烯醇（PVA）。
Effect of the size of zinc powder on the property of the coating was studied, and the result showed that the smaller size of zinc powder, the higher corrosion resistance of the zinc-chromium coating. 研究了鋅粉粒度對(duì)鋅鉻膜層耐腐蝕性能的影響，鋅粉粒度越小，所得鋅鉻膜耐腐蝕性能越強(qiáng)。
