Abstract
Wear and friction behavior of CuSnl2 bronze and CuSnl2 bronze/graphite-alumina composites have been investigated. The CuSnl2 composite shows excellent wear resistance and a lower coefficient of friction with respect to its matrix alloy. The tribological properties of the composite are mainly attributed to the thin layer of graphite at the surface of the wear track impeding the metal-to-metal contact. Thus, the coefficient of friction of the CuSnl2 composite is three times lower than that of the CuSnl2 bronze and the composite wear loss could not be detected after a 30 minutes wear test under a load and velocity of respectively 30 Kgs and 166 mm/s.
