摘要：

Wear induced by debris formation is studied under fretting and reciprocating sliding conditions. A sintered powder steel alloy is tested. Different compaction conditions inducing various surface porosities change the quantity of oil trapped during the final oil quenching and consequently modify the friction behavior. The study reveals a strong variation of the wear coefficient in relation to the friction coefficient. A low wear regime is observed for low friction coefficients, whereas high wear coefficients are observed for high friction values. This evolution is analyzed considering elastic, elastic shakedown and plastic shakedown conditions which are imposed on the material. The wear behavior of the studied tribosystem concludes that to better identify the intrinsic wear resistance of a material, the energy approach, which consists of a comparison of the wear volume to the cumulated dissipated energy is more appropriate.
