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 FeNi 3 , α-Co, and Cr 2 C. 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.

线能对CoCrFeNiBSi高熵合金激光熔覆涂层组织和力学性能的影响

非晶合金具有优良的机械性能，如高硬度和高耐磨性。利用各种激光线能量在H13钢表面制备了具有非晶相的CoCrFeNiBSi高熵合金。研究了熔覆层的显微组织、相、硬度和耐磨性。通过观察稀释率的变化，比较了不同熔覆层的玻璃形成能力。结果表明，涂​​层由非晶相和结晶相组成，其中含有FeNi 3 、α-Co和Cr 2 C。随着激光线能量的增加，涂层的稀释率增加，其中FeNi 3 、α-Co和Cr 2 C的含量增加。非晶相减少。非晶相含量高的涂层表现出令人满意的硬度和耐磨性。
