Abstract

Abstract:

The ceramic particle-reinforced high-entropy alloy was prepared by laser cladding forming technology. The hardness of the specimens was measured using an electronic Vickers hardness tester， and the effects of laser process parameters， reinforcement phase content of SiC ceramic particles， and Al element content on the hardness of the high-entropy alloy by laser cladding were analyzed. The results indicate that the hardness value of the high-entropy alloy’s cladding layer does not show a significant change with the increase in laser power. With the increase in scanning speed and powder feeding rate， there is a gradual upward trend in the hardness of the cladding layer. With the increase in the reinforcement phase content of SiC ceramic particles， lattice distortion occurs in the specimen； the micro-stress increases， and the hardness of the high-entropy alloy increases obviously. Al element has an obvious regulation effect on the properties of ceramic particle-reinforced high-entropy alloy and can further improve the hardness of the alloy.
