| 摘 要： | 选择轴承中使用最广泛的钢-钢摩擦副组成的摩擦体系,利用钢球的4球摩擦机,通过电子扫描电镜(SEM)观察磨斑直径和磨痕深浅,并对比摩擦系数,确定了纳米铜添加剂的最佳添加浓度为0.5%(质量分数).然后利用TLP接触疲劳试验机组模拟高速轴承的工况,考察了油溶性纳米铜添加剂的摩擦学性能;通过完全失效试验,验证纳米铜添加剂的实用性,并分析了其减摩机理.试验证明,0.5%纳米铜颗粒在轴承运转中不仅能够起到减摩抗磨的作用,而且能够延长轴承的使用寿命,提高近3倍.

| Abstract: | The optimal concentration of copper nanopaticle additive was 0.5wt% determined by using four ball wear test machine and scanning electron microscope.The bearing behavious at high speed was simulated by using contact fatigue machine TLP.The results show that copper nanoparticle additive of 0.5% not only plays the role of antifriction and wear resistance but also incresses the service life of bearing by a factor of 4 approximately. |
