Abstract
The discovery of multi-principal high-entropy alloys breaks the shackles of complex intermetallic compounds produced by the traditional multi-component alloys. Based on its unique high-entropy effect, a simple phase structure that exhibits excellent comprehensive performance can be generated. The high-entropy alloys exhibit many unique properties, including mechanical properties, high-temperature properties, and corrosion resistance. This study introduces the composition control of high-entropy alloys. Further, the research status of high-entropy alloy coatings, which are prepared using the laser cladding technology, with high hardness, thermal stability, high-temperature oxidation resistance, corrosion resistance, and wear resistance is reviewed. The development foreground of the laser cladding high-entropy alloy coatings is prospected.
