ABSTRACT:
In a combination of sliding members which are suitable for use in the compressor for an automotive air conditioner, one of the members consists of an aluminum alloy which contains silicone particles consisting solely of eutectic silicon; and the other sliding member consists of a fluoride resin which contains carbon fibers and a calcium compound. The surface of the aluminum alloy can be finished to a desired smoothness as it does not contain any excessively hard substance. Also, since a calcium compound which is intermediate between carbon fibers and teflon resin in hardness is distributed in the teflon resin, the tendency of the carbon fibers to attack the aluminum alloy is reduced, and the aluminum alloy can achieve a sufficient wear resistance even though it does not contain any primary crystal silicon particles having a high hardness. Furthermore, the calcium compound serves as a lubricant, and reduces friction between the two sliding members.
