在Q235钢表面电镀Ni-P合金,并在不同温度下对其进行热处理.以合金镀层试样为块材料,以GCr15钢为环材料,以含N-B-Mo抗磨剂的润滑油为介质,在M-2000型摩擦磨损试验机上进行摩擦磨损试验,采用X射线衍射仪、光学显微镜等研究了不同温度热处理的Ni-P合金镀层在不同抗磨剂含量的润滑油中的摩擦磨损特性,并分析了抗磨剂的抗磨机理.结果表明:随着热处理温度升高,Ni-P合金镀层的硬度先升高后下降,摩擦系数先下降后上升,当热处理温度为300℃时,Ni-P合金镀层的硬度最高,是基体的4.7倍;随着抗磨剂含量增加,Ni-P合金镀层磨损率呈现先降低后增加的趋势,当抗磨剂含量为3％时,磨损率最低,XRD谱结果表明含N-B-Mo抗磨剂润滑油的抗磨机理是在磨损表面生成了具有自润滑性能的BN相.
