摘要 采用电子束物理气相沉积方法在DD6单晶高温合金基体上制备了热障涂层,带涂层试样首先在1100℃空气气氛中分别进行了50h和100h热处理,然后在980℃/250MPa条件下进行持久实验,研究了持久断裂后合金与黏结层界面的互扩散行为、组织形貌以及断裂特征。结果表明:经过1100℃热处理,合金与黏结层之间的元素发生了互扩散,合金基体中Cr含量增加,而Re,Nb,Mo,Ta等元素向黏结层扩散;随热处理时间的增加,析出的不稳定相数量增多,持久断裂试样γ’相粗化程度增加;1100℃热处理带热障涂层持久断口为韧窝断口,与合金标准试样断口特征类似。

Abstract:Thermal barrier coatings were deposited on DD6 single crystal superalloy substrate by electron beam physical vapor deposition (EB-PVD), and then the specimens with coatings were subjected to heat treatment at 1100℃ in the air for 50 hours and 100 hours respectively before stress-rupture testing under the conditions of 980℃/250MPa. The elements interdiffusion behavior, microstructure and stress rupture characteristics were investigated after stress-rupture tests. The results show that elements interdiffusion between bond coat and the alloy occurs after high temperature heat treatment at 1100℃. DD6 alloy is rich of Cr, meanwhile Re, Nb, Mo and Ta diffuse from alloy to bond coat. The number of TCP and γ' phase coarsening extent increase with the heat treatment time. There is little effect on the stress rupture mechanism of DD6 single crystal superalloy with thermal barrier coatings, the stress rupture characteristic is dimple fracture.
