摘要

本研究乃以阴极电弧放电离子被覆技术在Inconel 6 0 0超合金上被覆Ni_Al镀层 ,与目前常用的高速融射CoCrAlY涂层同时进行 1 1 0 0℃高温循环氧化试验 ,比较二者的抗高温循环氧化性 .研究结果显示 :使用Ni52 Al4 8,Ni6 0 Al4 0 及Ni70 Al30 3种靶材分别得到富铝成份的Ni35Al6 5,Ni4 0 _Al6 0 以及Ni53Al4 7的镀膜 .在 1 1 0 0℃热循环氧化测试下 ,由于富铝的Ni_Al镀膜表面能快速生成Al2 O3层以阻止内部持续氧化 ,因而有较CoCrAlY涂层为低的氧化重量增加率

Abstract

A PVD process_cathodic arc plasma ion plating was used to deposit Ni_Al films on Inconel 600 superalloy. The oxidation behaviors of PVD Ni_Al coating and the thermal sprayed CoCrAlY coatings were revealed and compared by performing cyclic thermal oxidation test at 1 100 ℃ to evaluate its feasibility. Experimental results showed that the films with different compositions of Ni 62 Al 38 , Ni 63 Al 37 and Ni 69 Al 31 could be obtained when using Ni 52 Al 48 , Ni 60 Al 40 and Ni 70 Al 30 as targets, respectively. During the cyclic thermal oxidation test, the aluminum_rich Ni_Al films were beneficial to form an Al 2O 3 layer on the surface, which terminats oxidation rapidly to give a consequent oxidation mass change lower than that of thermal sprayed CoCrAlY coatings.
