Sintered Steel Microstructure And Wear Resistance

Mixing alloy elements of Ni,Mo,W in Fe-C-Cu alloy ,the sintered steel was prepared . The microstructure and wear resistance properties of the sintered steel had been studied. The influence of heat-treated technology and the alloy elements on the microstructure and the wear resistance had been studied and analyzed .Results of the experiments showed that the wear mechanisms of the sintered steel included abrasive wear,adhesive wear and fatigue wear, and it was the abrasive wear most important .It was the sintered steel mixed by Ni,Mo that was the best on the wear resistance , because of the great lot of Bainite; The sintered steel quenched and low temperature tempered mixed by Mo,W that was the best on the wear resistance ,because of the rigidity of the steel was the highest.
