摘要：

Amorphous alloys possess excellent mechanical properties such as high hardness and high wear resistance. CoCrFeNiBSi high-entropy alloys with amorphous phase have been prepared on the surface of H13 steel by utilizing various laser line energies. The microstructure, phase, hardness, and wear resistance of the cladding coatings were studied. The glass-forming ability of different cladding coatings was compared by observing the change on the dilution rate. The results show that the coatings consisted of an amorphous phase and a crystallization phase, which contained FeNi3, alpha-Co, and Cr2C. As the laser line energy was increased, the dilution rate of the coatings increased and the content of the amorphous phase decreased. Coatings with high content of amorphous phase showed satisfied hardness and wear resistance.
