Description
Summary:Wear and friction behavior of CuSn12 bronze and CuSn12 bronze /graphite-alumina composites have been investigated. The CuSn12 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 CuSn12 composite is three times lower than that of the CuSn12 bronze and the composite wear loss could not be detected after a 30 min wear test under a load and velocity of respectively 30 Kgs and 166 mm/s.
