Abstract

Abstract: Effect of ultrasonic shot peening on NiCoAlFeCrMoSi high entropy alloy coating prepared on the surface of magnesium alloy was investigated in order to enhance the corrosion and wear resistance of the coating. The results show that with the increase of ultrasonic shot peening time (0-800 s), the surface roughness of the coating decreases and then increases, the porosity decreases, and the corrosion resistance and wear resistance show a trend of first increasing and then decreasing. When the ultrasonic shot peening time is 400 s, the coating has the best corrosion resistance and wear resistance. Compared with the coating that is not shot peened, the average surface hardness is increased by 50 HV0.2, the surface roughness reduced by 53.82%, the corrosion current density decreases from 3.012×10^-5 A/cm² to 9.80 μA/cm², and the wear volume is reduced by 26.8%.

Key words: coating, ultrasonic shot peening, surface roughness, corrosion resistance, wear resistance
