| 摘 要： | 对电刷镀Ni - P合金镀层的高温摩擦磨损性能进行了研究.实验结果表明,在20CrMo钢基体上,电刷镀Ni - P合金镀层能有效降低试样在高温(450 ℃)下的摩擦因数,减小高温磨损量.其中,12 min电刷镀试样在高温摩擦测试前80 min内,摩擦因数基本维持在平均值约0.30,仅为20CrMo钢基体(0.60)的50%;80～120 min因镀层局部被磨损穿透,其摩擦因数缓慢增长;120 min后,基本维持在平均值约0.50,测试完成后质量磨损量为同等测试条件下20CrMo钢基体的19.99%;24 min电刷镀试样在450℃下摩擦测试180 min的整个过程中,摩擦因数均较稳定,平均值为0.30,高温摩擦磨损测试后的质量磨损量仅为20CrMo钢基体的6.36%.

| Abstract: | High-temperature friction and wear properties of Ni-P coatings prepared by electro brush plating were investigated.The experimental result shows that Ni-P coatings prepared by electro-brush plating on 20CrMo steel matrix can effectively reduce the friction coefficient and wear loss.Among the samples,the friction coefficient of 12 minute electro-brush plating sample was about 0.30 in the first 80 minutes of high temperature wear test,only 50 percent of that of the 20CrMo steel,then it increased from 80 to 12... |
