在镍基单晶高温合金基体上采用化学气相沉积法制备铂铝金属黏结层,并采用电子束物理气相沉积制备氧化钇部分稳定化的氧化锆(YSZ)陶瓷面层。研究了黏结层相组成对热障涂层循环氧化行为的影响,借助扫描电子显微镜(SEM)、X射线能谱分析(EDS)和X-射线衍射分析(XRD)等方法分析涂层的相结构、显微组织和化学成分。结果表明:黏结层主要成分包括Ni、Al、Pt、Co和Cr元素并由β-(Ni,Pt)Al相和PtAl2相组成;经热循环测试后,涂层在热生长氧化物(TGO)和黏结层内部及其界面可能出现剥离;随着热暴露时间的延长,TGO层处的残余应力总体上呈现出逐渐减小的演变趋势;控制铂铝黏结层前驱体活性、Pt/Al元素含量、抑制脆性PtAl2相生成、改善TGO层/黏结层界面韧性和降低TGO层应力应变水平可有效延长铂铝黏结层体系热障涂层的热循环寿命。 |

The(Ni, Pt) Al bond coats were prepared on the surface of nickel base single crystal superalloy by chemical vapor deposition(CVD), and then YSZ ceramic coats were directly deposited on the surface of bond coats by electron beam physical vapor deposition(EB-PVD).The influence of phase constituent of bond coat on the cyclic oxidation behavior of (Ni, Pt)Al/YSZ thermal barrier coatings was investigated in detail. The phase structure, morphology and chemical composition of the coatings were analyzed. The experimental results show that the bond coat is mainly composed of β-(Ni,Pt)Al and PtAl2 phases and the contents of the asdeposited bond coat are primarily including Ni, Al, Pt, Co and Cr elements. The spallation location of the TBCs probably occurs at the interface of TGO layer and bond coat, inside of TGO layer and within the bond coat. After thermal cycling test, it is found that the spallation may occur in the interior and interface of TGO and adhesive layer. With the extension of thermal exposure time, the residual stress located at the TGO layer decreases gradually in total. Therefore, controlling the precursor activity, Pt/Al element content, inhibiting the formation of brittle PtAl2 phase, improving the interfacial toughness of TGO layer/bonding layer, and reducing the stress-strain level of TGO layer are important ways to extend the thermal cycling life of(Ni, Pt)Al/YSZ thermal barrier coatings. |
