摘 要: 對Zr-8Al合金進行化學復合鍍Ni-P-ZrO2處理，并研究OP-10和LAS分散劑單獨以及復合添加對復合鍍層的沉積效率、顯微形貌和耐腐蝕性能的影響。結果表明：OP-10添加量為10 mL/L時，復合鍍層沉積速率最高，OP-10和LAS復合添加制備的復合鍍層沉積速率最低。OP-10和LAS復合添加制備的復合鍍層胞狀結構均勻細小，表面質量最好。與Zr-8Al合金基體相比，OP-10和LAS復合添加制備的復合鍍層在3.5% NaCl(質量分數)溶液中的自腐蝕電位正移，自腐蝕電流最小，耐腐蝕性能最佳。

Abstract:The electro-less Ni-P-ZrO2 composite plating was prepared on Zr-8Al alloy with OP-10 and LAS separate and compound additions. The deposition rate, microstructure and corrosion resistance in 3.5% NaCl solution of electro-less composite platings were investigated. The results show that the deposition rate of electro-less Ni-P-ZrO2 composite plating prepared with OP-10 is highest while that of plating prepared with OP-10 and LAS is lowest. The cellular of electroless Ni-P-ZrO2 composite plating is fine and uniform which indicates the quality is super. Compared with that of Zr-8Al alloy, the self corrosion potential of the electroless Ni-P-ZrO2 composite plating prepared with OP-10 and LAS is shifted positively and the self corrosion current density is minimum so that its corrosion resistance is the best.
