Abstract

Abstract

The cladding layer of FeCoCrNiTiMo high entropy alloy with TaC nanoparticle was prepared on the surface of 45# steel by laser cladding. The phase composition, microstructure and the cross-section hardness of the cladding layer were analyzed and tested by X-ray diffraction (XRD), scanning electron microscope (SEM), energy dispersive spectrometer (EDS) and microhardness tester. Studies show that by adding TaC nanoparticles to FeCoCrNiTiMo high entropy alloy cladding layer, the phase structure of the alloy is mainly composed of body-centered cubic FeCrNi solid solution and face-centered cubic NiCrCoMo solid solution, and contains a very small amount of intermetallic compounds. The Vickers hardness (HV) of cladding layer reaches 1058.89, which is twice the hardness of the base material.
