| 摘 要： | 采用常规粉末冶金方法制备无铅含铋铜-钢双金属轴承材料,在HDM-20端面摩擦磨损试验机上进行边界润滑条件下的摩擦磨损试验,分析无铅含铋铜-钢双金属轴承材料的减摩、抗粘着性能及其承载能力,并与典型的铜铅轴承材料(Cu10Sn10Pb)及铜锡合金材料的性能进行对比.结果表明:无铅含铋铜轴承材料中的低熔点组元铋(熔点为271℃)能阻碍因油膜破裂而引起的摩擦副局部区域的直接接触,体现出较好的减摩和抗粘着性能;当铋含量为3.0%(质量分数)时,无铅含铋铜基轴承材料的减摩,抗粘着咬合性能良好,承载能力较强,接近或优于典型铜铅轴承材料的性能.

| Abstract: | Lead-free Bi-contained copper-steel bimetal bearing materials were prepared by powder metallurgy method,their friction and wear tests were conducted by using the HDM-20 tribometer under boundary lubrication conditions.The anti-friction,anti-adhesion and load carrying capacity of the lead-free Bi-contained copper matrix bearing materials were also analyzed and compared with those of the typical copper-lead bearing material(Cu10Sn10Pb).The results show that the addition of Bi can improve the anti-friction and... |
