Abstract

Abstract:

In order to improve the wear resistance of hot?rolled high speed steel work rolls， Inconel 625 alloy coatings with 0%， 10%， 20%， and 30% （Ti，W）C content were prepared on ductile iron substrate by laser cladding technology. The effect of （Ti，W）C particles on the microstructure， hardness and wear resistance of the coatings was investigated. The （Ti，W）C particles are uniformly distributed in the coating， and have a good combination with the Inconel 625. The hardness of the coating increases from HV_0.2280 to HV_0.2424 with the increase of the （Ti，W）C particle content. In the process of friction and wear， the （Ti，W）C particles， as hard phases， inhibit the local plastic deformation of the material during wear. The wear amount of Inconel 625 alloy coating containing 30% （Ti， W）C particles is only 0.015 m³， and the average friction coefficient is 0.061 6. It has been proved that the hardness and wear resistance of Inconel 625 alloy coating are significantly improved and the friction coefficient is reduced by adding a reasonable amount of （Ti，W）C particles.

Key words: laser cladding, （Ti，W）C particles, Ni-（Ti，W）C coating, microstructure, hardness, wear resistance
