  • The ceramic layers were cladded on W6Mo5Cr4V2 high speed steel surface with a 2kW CO2 laser,and the net of three dimension ceramic layers are formed.The steel was quenched and tempered The test results indicate that the high strength and toughness of the steel combines with their properties of the ceramic layers forming a well distribution. The highesthardness of the layers can reach 1887HV,and the wear resistances are increased (3～7) times compared to those of the steel in common heat treatment. The high temperature hardness and temper stability are enhanced,too.

Abstract: The ceramic layers were cladded on W6Mo5Cr4V2 high speed steel surface with a 2kW CO2 laser,and the net of three dimension ceramic layers are formed.The steel was quenched and tempered The test results indicate that the high strength and toughness of the steel combines with their properties of the ceramic layers forming a well distribution. The highesthardness of the layers can reach 1887HV,and the wear resistances are increased (3～7) times compared to those of the steel in common heat treatment. The high temperature hardness and temper stability are enhanced,too.
