Abstract:The AlYSi coatings were deposited by arc ion plating on K465 superalloys.The high temperature oxidation behavior of K465 alloys with or without coating at 1100℃ was studied.By means of SEM,EDX and XRD,the surface and section of coating were analyzed.The results show that the coating is composed of β-NiAl phase,the Al2O3 protective scale is formed out of the coating and observably improves the high temperature oxidation resistance of K465 superalloys.
