Dry Sliding Wear Behavior of Fe-Ni-Mo-C-Cr Powder Sintered Structural Steel

摘要：

Fe-Ni-Mo-C-Cr system powder metallurgy in the assintered was investigated on pin-on-rolling wear tester for their dry sliding wear behavior．The morphology of worn surfaces and wear mechanism were analysed by SEM．Results show the hot-forging deformation quenching and tempered considerably decreased the porosity and improved wear resistance， and compare with quenching microstructure，tempered microstructure has high wear resistance and match of strength-toughness.Fe-2.0Ni-0.4Mo-0.5C-0.6Cr alloy presented best wear characteristics．SEM observations of the worn surface revealed microploughing and plastic deformation and crack were the basic dry．sliding wear morphology,and oxidative wear and delamination wear are dominant wear mechanism．
