摘 要: 对Zr-8Al合金进行化学复合镀Ni-P-ZrO2处理,并研究OP-10和LAS分散剂单独以及复合添加对复合镀层的沉积效率、显微形貌和耐腐蚀性能的影响。结果表明:OP-10添加量为10 mL/L时,复合镀层沉积速率最高,OP-10和LAS复合添加制备的复合镀层沉积速率最低。OP-10和LAS复合添加制备的复合镀层胞状结构均匀细小,表面质量最好。与Zr-8Al合金基体相比,OP-10和LAS复合添加制备的复合镀层在3.5% NaCl(质量分数)溶液中的自腐蚀电位正移,自腐蚀电流最小,耐腐蚀性能最佳。

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.
