Cooperating slidable aluminum alloy members

Claim 1

Cooperating slidable aluminum alloy members comprising first and second slidable aluminum alloy members that slide relative to each other, said first slidable aluminum alloy member having a slide portion of a fiber-reinforced aluminum alloy, comprised of an aluminum alloy and a reinforced fiber, said reinforcement fiber being a fiber mixture comprised of an alumina fiber of a volume content of 8.0 to 20.0% and a carbon fiber of a volume content of 0.3 to 15.5%, said alumina fiber having an alpha rate from 10.0% to 50.0%, the alumina fiber having a content of shots with an average particle size of 150 μm or more that are 2.5% or less by weight, said second slidable aluminum alloy member having a slide surface slidably engaging said slide portion of said first slidable aluminum alloy member, said slide surface being provided with a layer of heat resistant synthetic resin of thickness from 5 to 50 μm in which are dispersed a solid lubricant and an abrasion resistance improving agent, said solid lubricant including at least one selected from a group consisting of MoS 2 particles, BN particles, carbon particles and polytextrafluoroethylene particles, and said abrasion resistance improving agent being a copper containing fine substance.
