Abstract

Abstract: In order to improve the tribological properties of A100 steel, pure A100 steel alloy powder and W6Mo5Cr4V2/A100 alloy powder with 10%, 17%, 23%, respectively, tungsten-molybdenum high-speed steel were prepared by gas atomization, then powder metallurgy process was used to prepare W6Mo5Cr4V2 /A100 composites. Effect of W6Mo5Cr4V2 steel content on mechanical properties and tribological properties of the composites was studied, and wear mechanism was discussed. The results show that as the content of W6Mo5Cr4V2 steel increases, the hardness of the composites increases first and then decreases, the friction coefficient and wear rate are reduced to varying degrees, but the density and toughness of the material are slightly reduced. When the content of W6Mo5Cr4V2 steel is 17%, the tribological properties of the composite material are optimal, which is closely related to its excellent microstructure and mechanical properties.

Key words: W6Mo5Cr4V2/A100 composites, powder metallurgy, tribological properties
