摘　　要：The corrosion resistance of Al0.2CoCrFeNi high-entropy alloy(HEA) film deposited by magnetron sputtering was investigated and compared with that of Al0.2 CoCrFeNi HEA bulk and G115 alloy.The HEA film is composed of face-centered cubic with nanoscale grain size.The HE As(film and bulk) exhibit higher electro-chemical corrosion resistance than the G115 alloy in 3.5 wt% NaCl solution.
