高熵合金是一类具有最小5个基本元素在等原子或近等原子比下，同时具有4个核心效应的新型材料——高熵效应、缓慢扩散效应、严重晶格畸变效应和鸡尾酒效应。这些影响导致了高熵合金的一些明显的特性。激光熔覆法作为一种表面涂层方法，具有工艺稳定性好、可重复性好、工艺参数控制好、熔覆层与基材之间具有良好的冶金结合性等独特的特点。本文综述了迄今为止在激光熔覆高熵合金涂层参数化研究方面所开展的各种研究工作。
The high entropy alloy is the new class of materials having minimum five principle elements in equi-atomic or near equi-atomic ratio along with four core effect high entropy effect, sluggish diffusion effect, severe lattice distortion effect and cocktail effect. These effects lead to some distinct characteristic of high entropy alloy. As a kind of surface coating method, laser cladding method is superior to others due to its unique characteristics such as process stability, improved repeatability, better control on process parameters and the good metallurgical bonding between the clad layer and base material. The paper summarizes various research works carried out so far in the area of parametric investigation of laser cladded high entropy alloy coatings.
