Chromium Electroplating Using Reduced Product of Hexavalent Chromium
-
摘要: 研究了不同還原劑與六價鉻的還原反應和各種反應條件對還原率的影響。討論了反應歷程,確定了最佳反應條件。這種還原產物可以做為無毒性電鍍鉻的鉻源。使用這種三價鉻化合物進行了電鍍試驗,獲得了厚度超過100μm的鍍層。Abstract: Effects of different reducers as well as various reaction conditions on reducing of hexavalent chromium were investigated. The reaction process was discussed and the optimum reaction conditions were determined. The reaction product can serve as chromium source of nontoxic chromium plating and coating thicker than 100μm was obtained.
