Abstract

Graphite as a solid lubricant was incorporated in a Al-Si eutectic alloy by a liquid metallurgy technique. The pin-on-disc wear test unit was used to determine the friction and wear characteristics of the composites in the speed and bearing pressure ranges of 0.9 to 4.4 $ms^{-1}$ and 0.15 to 1.02 MPa respectively. The pins of the composites were slid against a hardened (63 HRC) AISI-SAE 52100 steel disc under dry conditions for a distance of 5000m. SEM features of the worn surfaces were correlated with the ob served wear data. An attempt was made to determine the effect of graphite type, modification of the matrix and hot working on wear behaviour of the composites. It was found that more than the graphite type, the silicon size influences the wear.
