摘　　要：研究了稀土氧化物Y_2O_3、Pr_6O_(11)对氨基磺酸盐电镀镍层性能的影响。基础镀液组成和工艺条件为:氨基磺酸镍400~500 g/L,氯化镍5~15 g/L,硼酸30~40 g/L,p H 3.5~4.5,温度50~60°C,电流密度8.0 A/dm^2,时间5 min。镀液中添加1.00 g/L Y_2O_3或0.05 g/L Pr_6O_(11)时,可获得表面平整、均匀,晶粒细小的镀层,它们的显微硬度分别比纯镍镀层大161 HV和77 HV。但添加1.00 g/L Y_2O_3时的沉积速率比添加0.05 g/L Pr_6O_(11)时高50%,并且前者所得镀层更平整。The effects of rare earth oxides Y2O3and Pr6O11on properties of nickel coatings electroplated from a bath comprising nickel sulfamate400-500g/L,nickel chloride5-15g/L,and boric acid30-40g/L at temperature50-60°C,pH3.5-4.5,and current density8.0A/dm2for5min were studied.The nickel coating obtained with1.0g/L Y2O3and that with0.05g/L Pr6O11both feature small grain size,and their microhardness are161HV and77HV higher than that of a pure nickel coating.The electrodeposition rate with the addition of1.00g/L Y2O3in bath is50%higher than that with0.05g/L Pr6O11,and the coating obtained with1.00g/L Y2O3is smoother.
