Abstract

The variation in the coefficient of friction with sliding distance for different sliding conditions for both similar and dissimilar metals in a crossed-cylinder geometry is presented. Metallic transfer due to adhesion at the early stage of sliding controls the coefficient of friction of a soft metal sliding on a hard metal. Debris generated in the wear process are formed of the soft metal only. For a hard metal sliding on a soft metal friction is influenced by the ploughing action. There is mutual transfer of metals between the sliding surfaces and the generated debris in this case are formed of both metals. These observations are confirmed by scanning electron microscopy and electron probe microanalysis.
