摘　　要：研究了化学镀 Ni-P合金在 CO2 溶液中的腐蚀磨损行为。结果表明 ,CO2 浓度增大 ,载荷增加 ,滑动速度增加 ,化学镀 Ni-P合金的腐蚀磨损速率增大、自腐蚀电位负移 ;CO2 浓度增大 ,载荷减小 ,滑动速度降低 ,化学镀 Ni-P合金的摩擦系数增大。同样条件下 ,化学镀 Ni-P合金比 G1 0 5钢具有更高的耐腐蚀磨损性。The corrosive wear behavioures of eletroless Ni P coating in CO 2 solution have been studied in the paper.The results show that the corrosive wear rate of eletroless Ni P coating increases and the corrosion potential of the coating decreases with increasing CO 2 concentration,mormal load and sliding speed.The friction coefficient of eletroless Ni P coating increase with increasing of CO 2 concentration,decreasing of mormal load and sliding speed.At the same condition,eletroless Ni P coating has higher anti corrosive wear ability than that of G105 steel in CO 2 solution.
