摘　　要：采用电弧离子镀技术在K465镍基高温合金基材上制备了AlYSi沉积-扩散型涂层,研究了K465合金和AlYSi涂层在1100℃下的高温氧化行为。利用SEM,EDX,XRD对氧化后的涂层表面和截面进行分析,结果表明:AlYSi涂层主要由-βNiAl相组成,氧化过程中涂层表面形成了Al2O3保护膜,显著提高了合金的抗高温氧化性能。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.
