| Abstract: |
| HIGH entropy alloys (HEAs) can be widely used in aerospace, biomedicine, new energy, nuclear industry, etc. for their high strength and hardness, superior wear resistance and corrosion resistance. However, the cost of HEAs is expensive due to the high price of each principal component. HEA coatings developed based on HEA theory and modern surface technology can not only reduce preparation cost, but also obtain superior properties. The work aims to prepare FeCoCrNiAl HEA coatings under a power of 15, 20 and 25 kW by atmospheric plasma spraying (APS) and investigate the effects of temperature on microstructure and wear resistance of HEA coatings. |
