摘要
采用电化学方法对W6Mo5Cr4V2电抛光工艺进行了研究，抛光溶液采用无铬酸盐的磷酸-硫酸体系，添加高分子聚乙二醇。抛光溶液组成为H3PO4（85％）500g，H2SO4硫酸（98％）130g，聚乙二醇130g，甘油30g，工艺条件：75～95℃，阳极电流密度8～15A·dm^-2。研究结果表明：聚乙二醇能有效地形成粘膜，明显提高W6Mo5Cr4V2电抛光的效果。该工艺减少了环境污染，降低了成本，可以使W6Mo5Cr4V2表面达到镜面光亮的效果。
An electropolishing process for W6Mo5Cr4V2 is studied by using electrochemical method. The polishing solution is of chromate-free phosphoric acid-sulfuric acid system with additive of polyethylene glycol,which consists of 500 g H3PO4 （85%）, 130 g H2SO4 （98%）, 130 g polyethylene glycol（ 18.5% aqueous solution ） and 30 g glycerin. The operation temperature is 75 - 95℃ and anodic current density 8 - 15 A·dm^-2. The research results show that polyethylene glycol can effectively form a sticky film on the surface of W6Mo5Cr4V2, so that the polishing effect is obviously improved. By using this process, environmental pollution and production cost can be reduced,and mirror-like appearance obtained on the surface of W6Mo5Cr4V2.
