摘要
研究了用粉末冶金方法生产的非金属含量较高的摩擦材料在模拟空间状态下的摩擦磨损性能。重点探讨了材料中非金属组元(特别是摩擦组元、润滑组元)对材料的摩擦性能及稳定度的影响。结果表明在模拟空间状态下, 无论是铁基还是铜基, 或是Fe/Cu基的摩擦材料仍然遵循在大气状态下的规律。研究结果表明除宇宙射线粒子的影响未考虑外, 模拟空间状态下摩擦性能最稳定的是具有一定润滑性能, 且非金属成分的体积分数比较高的铜基粉末冶金摩擦材料。
Friction and abrasion properties of the abrasion material with high non-metal content processed by powder metallurgy were investigated in simulated space state. Effects of the non-metal constituents, particularly friction and lubricant constituents on the friction stability of the materials were mainly discussed. The results show that in the simulated space state, Cu-based, Fe-based or Fe/Cu-based abrasion materials all present behaviors similar to those in the ambient state. Under the simulated space state without considering the cosmic rays factor, the results show that the material system with the most stable abrasion property is the Cu-based materials with high non-metal constituent and some lubricant property.
