BN和MoS_2对镍基材料摩擦磨损性能的影响
|
摘要
通过热压烧结制备了含不同质量分数润滑剂(0%、10%MoS_2、5%MoS_2+5%BN和10%BN)的镍基材料,利用销盘摩擦磨损试验机对4种镍基材料在载荷30～60 N、滑动速度0.35～0.58 m·s~(-1)(300～500 r·m~(-1))条件下进行摩擦磨损实验,通过扫描电镜观察磨损表面形貌,分析了不同润滑剂对镍基材料抗磨损性能的影响。结果表明:由于Mo S2与基体之间结合良好,含有10%Mo S2润滑剂的镍基材料具有较低且平稳的摩擦系数和最低的磨损率;由于BN与基体之间结合松散,含10%BN润滑剂的镍基材料在较高载荷和滑动速率下具有相对较高的摩擦系数和磨损率。
The nickel-based materials added with the different solid lubrications in the mass fraction as 0%, 10%MoS_2,5%Mo S2+5%BN, and 10%BN were prepared by hot press sintering, respectively. The friction and wear properties of nickel-based composites were tested by pin disc friction and wear testing machine at the load of 30～60 N in the sliding speed of 0.35～0.58 m·s~(-1)(300～500 r·m-1), the wear surface morphology of Ni-based materials were observed by scanning electron microscopy(SEM), and the effects of different solid lubrications on the wear resistance of nickel-based materials were studied. The experimental results indicate that, the nickel-based composites with 10%MoS_2 show the lower and stable friction coefficients and the lowest wear rates due to the good combination between MoS_2 and matrix; however, the composites with 10%BN show the relatively high friction coefficients and wear rates under high load and sliding rate due to the loose combination between BN and matrix.
