摘要/Abstract

摘要： （Yb_0.1Gd_0.9）₂Zr₂O₇（YbGdZrO）稀土复合氧化物是一类适用于1 200 ℃以上应用的新型热障涂层（TBCs）材料。采用电子束物理气相沉积（EB-PVD）工艺在NiCoCrAlYHf及（Ni,Pt）Al粘结层表面分别沉积YbGdZrO陶瓷层,制备出两种不同粘结层体系的TBCs试样,并对涂层的显微形貌、化学成分、相结构、残余应力和热冲击行为进行了表征分析。结果表明,NiCoCrAlYHf粘结层表面高低起伏,所沉积的陶瓷层呈“菜花状”织构,紊乱度较高;（Ni, Pt）Al粘结层表面呈平缓的“背脊”形貌,所沉积陶瓷层的柱状晶排列紧密且平整度趋于一致;两种涂层的陶瓷层中Gd和Zr元素含量均与靶材成分较为接近,但Yb元素受沉积温度影响相差较大;随热冲击次数增加,NiCoCrAlYHf/YbGdZrO涂层表面显微裂纹萌生并扩展,且出现点蚀坑,（Ni, Pt）Al/YbGdZrO涂层仍较为平整,无显微裂纹和烧结致密化现象;热冲击1 000次后,两种涂层中均出现热生长氧化物（TGO）层,继续热冲击至2 500次时,（Ni,Pt）Al粘结层体系的TGO层平均厚度增量仅为1.08μm;NiCoCrAlYHf/YbGdZrO涂层的TGO层残余应力均比同等条件下（Ni,Pt）Al/YbGdZrO的小;两种TBCs的陶瓷层组成元素均已内扩散至粘结层,并少量存留在TGO层内,（Ni,Pt）Al/YbGdZrO涂层所形成的Al₂O₃膜对Gd元素表现出更强的阻扩散作用。

Abstract: The rare earth composite oxide of （Yb_0.1Gd_0.9）₂Zr₂O₇ （YbGdZrO） is a new kind of thermal barrier coatings （TBCs） materials suitable for applications above 1 200 ℃. TBCs specimens with different types of bond layers were prepared by depositing YbGdZrO ceramic coatings onto the surface of bonding layers of NiCoCrAlYHf or （Ni,Pt）Al by electron beam physical vapor deposition （EB-PVD） technique. The microstructure, chemical composition, phase structure, residual stress and thermal shock behavior of the coatings were characterized and analyzed. The results show that the surface of NiCoCrAlYHf bond layer is undulating, and the ceramic layer deposited on it has cauliflower-like texture and a high degree of disorder. The surface of the （Ni, Pt） Al bond layer shows a smooth "back ridge" morphology, and the columnar crystals of the deposited ceramic layer are tightly arranged and the flatness tends to be consistent. The contents of Gd and Zr elements in ceramic layer of the two TBCs specimens are close to that of the original ingot, while the Yb element content is greatly affected by the deposition temperature. With the increase of thermal shock times, the micro-cracks on the surface of NiCoCrAlYHf/YbGdZrO coating initiate and propagate, and pitting pits appear. The （Ni,Pt）Al/YbGdZrO coating is still relatively flat, without micro-cracks and sintering densification. Thermally grown oxide （TGO） layer appears in both coatings after 1 000 times of thermal shock. When the thermal shock reaches to 2 500 cycles, the averaged thickness increment of TGO layer growing on top of （Ni,Pt）Al bond coat is only 1.08 μm. The TGO residual stress of NiCoCrAlYHf/YbGdZrO TBCs is smaller than that of （Ni,Pt）Al/YbGdZrO specimen under the same condition. The ceramic layer elements of both TBCs have diffused to the bond coats, and a small amount remains in the TGO layer. Differently, the Al₂O₃ film formed by （Ni,Pt）Al/YbGdZrO TBCs shows stronger diffusion resistance for Gd element.
