TiSi2 doped Gd2Zr2O7 ceramic material, preparation method and thermal barrier coating
The invention discloses a TiSi2-doped Gd2Zr2O7 ceramic material, a preparation method and a thermal barrier coating, and the design idea is that the Gd2Zr2O7 thermal barrier coating ceramic material is doped by using the TiSi2 material with excellent fracture toughness, and the order degree of the original internal crystal structure is changed, so that the toughening effect is achieved; and meanwhile, related thermal physical properties such as thermal expansion coefficient and thermal conductivity can be improved, so that related problems existing in the original Gd2Zr2O7 material are solved. Compared with the prior art, the Gd2Zr2O7 thermal barrier coating ceramic material and the preparation method thereof have the following remarkable advantages that the Gd2Zr2O7 thermal barrier coating ceramic material doped with different contents of TiSi2 can still keep good high-temperature phase stability and relatively good sintering resistance at 1500 DEG C; the high-temperature-resistant thermal barrier coating ceramic layer material has higher thermal expansion coefficient, lower thermal conductivity and better fracture toughness at high temperature, and is suitable for being used as a high-temperature-resistant thermal barrier coating ceramic layer material.
本发明公开了一种TiSi2掺杂Gd2Zr2O7陶瓷材料、制备方法及热障涂层，其设计思想是利用TiSi2这种断裂韧性优良的材料对Gd2Zr2O7热障涂层陶瓷材料进行掺杂，改变原内部晶体结构的有序度，以此来达到增韧效果，同时也可以改善热膨胀系数、热导率等相关热物理性能，从而解决原Gd2Zr2O7材料存在的相关问题。本发明对比已有发明和技术具有以下显著优点：掺杂不同含量的TiSi2后的Gd2Zr2O7热障涂层陶瓷材料在1500℃下仍然能够保持良好的高温相稳定性和较好的抗烧结性，与传统的Gd2Zr2O7热障涂层陶瓷层材料相比，本发明在高温下具有更高的热膨胀系数以及更低的热导率，同时具有更好的断裂韧性,适合作为耐高温的热障涂层陶瓷层材料。
