Unidirectional sliding friction and wear tests of an Al-Si alloy impregnated graphite composite (Al-Gr) pin in contact with a bearing steel disk were conducted at a constant contact load as a variable of relative humidity (RH) in air and argon gas, and in ion-exchanged water, aimed at investigating friction and wear characteristics of the composite expected as an advanced sliding material. The influence of oxygen and water vapor in the atmosphere were mainly investigated. The composite has a minimum in friction and wear in the middle RH range, since compacted films consisting of Al alloy wear debris and graphite powders are zonally formed on the disk sliding surface, preventing adhesion due to metal-to-metal contact.Friction and wear characteristics of an alumina short fiber-reinforced Al-Si alloy matrix composite (AFRMMC) in contact with Al alloy (JIS AC8A or A2017) were elucidated in lubricating oil. Friction coefficient (μ) rapidly increases at a certain load for the AFRMMC against A2017 in machine oil and engine base oil. However, the load level where μ rapidly increases for the AFRMMC against AC8A does not appear, although the frictional mode transits to the boundary lubrication.Fretting characteristics of the Al-Gr and AFRMMC in contact with bearing steel were also investigated from test results in air as a variable of relative slip amplitude. The Al-Gr exhibited good tribological performance during fretting over the whole range of relative slip amplitude tested.

在空气、氩气和离子交换水中，以恒定接触载荷和相对湿度（RH）为变量，对浸渍铝硅合金石墨复合材料（Al-Gr）销轴与轴承钢盘进行了单向滑动摩擦磨损试验，旨在研究该复合材料作为先进滑动材料的摩擦磨损特性。重点研究了大气中氧气和水汽对大气中的CO2浓度的影响。该复合材料在中RH范围内摩擦磨损最小，这是因为在摩擦片滑动表面上形成了由Al合金磨屑和石墨粉组成的致密膜，氧化铝短纤维增强铝硅合金基复合材料（AFRMMC）与铝合金接触的摩擦磨损特性（JIS AC 8A或A2017）的润滑油中的溶解度。在一定载荷下，AFRMMC与A2017在机油和发动机基础油中的摩擦系数μ迅速增大。在空气中，以相对滑移幅度为变量，研究了Al-Gr和AFRMMC与轴承钢接触时的微动特性。在微动过程中，Al-Gr表现出良好的摩擦学性能，在整个范围内的相对滑移幅度测试。
