摘要:

 界面结合强度是热障涂层最为重要的力学指标之一。目前,十字交叉法能够同时测定涂层界面拉伸与剪切结合强度而得到广泛应用。然而,十字交叉法仍存在不足之处。本研究对十字交叉试样与夹具进行改进,采用改进后的试样与夹具对8YSZ热障涂层进行测试。结果表明:8YSZ热障涂层的界面拉伸结合强度为(23.68±1.56) MPa,界面剪切结合强度为 (25.88±2.14) MPa,其破坏形式均为界面/涂层破坏;改进十字交叉法剪切强度测试时,界面受到的是单一的剪切力,测试不再受到粘结剂强度的限制;改进十字交叉法避免了在拉伸强度测试过程中夹具与样品摩擦力的影响,提高了测量结果的准 确性。

 

 Interfacial bond strength is one of the vital mechanical properties of thermal barrier coating. The cross-bonded method, which can measure the interfacial tensile and shear bond strength, has attracted recent attention. However, some imperfects of this method were found in practice. In this paper, improved cross-bonded sample and fixture were represented and the tests were carried out to 8YSZ thermal barrier coating. The results show that the tensile bond strength of 8YSZ thermal barrier coating is (23.68±1.56) MPa and the shear bond strength is (25.88±2.14) MPa, and the type of fracture is both interface/coating fracture. In the shear tests, interface is subjected to a pure shear stress, without the influence from the strength of adhesives. And an improved technique effectively avoids a possible friction between the fixture and sample in tensile bond strength test, thus enhancing the accuracy of results.
