Influence of porosity on the sliding wear behavior of sintered Fe-1.5Mo-0.7C steels

摘要: Fe-1.5Mo-0.7C steels with different porosity can successfully be prepared by using traditional compacting, vacuum sintering, and in part Hot Isostatically Pressing (HIPing). Their dry sliding wear behavior both as-sintered heat treated states were investigated. When is lower than 6.2%, further decreases of have less influence on the coefficient steels. Pores sintered collect debris during rubbing process, therefore disadvantage process due to poor hardness mechanical strength caused high partly compensated for. During three types mechanisms (i.e., oxidational wear, abrasive delamination wear), while are main regimes Oxidation leads meantime oxides attached surface intense system. Abrasive which result flake debris, responsible for coefficients.
