Cerium-doped yttrium titanate thermal barrier coating material and preparation method thereof
The invention belongs to the technical field of thermal barrier coatings, and particularly relates to a cerium-doped yttrium titanate thermal barrier coating material and a preparation method thereof. The yttrium titanate material applied to the fields of gas sensing, photovoltaics and microwaves is modified by doping a rare earth Ce element and then is used as a ceramic layer of the thermal barrier coating, the chemical composition of the ceramic layer material is Y2 (CexTi1-x) 2O7, and x is equal to 0.1-0.3; by doping Ce ions, the heat insulation performance of the yttrium titanate material can be improved, and meanwhile, the bonding strength between the yttrium titanate material and a matrix is obviously improved, so that the cerium-doped yttrium titanate ceramic thermal barrier coating material with excellent mechanical property and heat insulation performance is provided. On the basis of ensuring high-temperature phase stability and low thermal conductivity, the bonding strength between the thermal barrier coating and the matrix is improved, and the thermal barrier coating material can be suitable for an alternative material of a high-temperature thermal barrier coating of an aviation turbine engine and has the advantages of being low in cost, simple in process, easy to control and suitable for industrial mass production.
本发明属于热障涂层技术领域，具体涉及一种铈掺杂钛酸钇的热障涂层材料及其制备方法。本发明将应用于气体传感、光伏和微波领域的钛酸钇材料通过掺杂稀土Ce元素改性进而用作热障涂层的陶瓷层，陶瓷层材料化学组成为Y2(CexTi1‑x)2O7，其中x＝0.1～0.3；Ce离子的掺杂在能够提升钛酸钇材料隔热性能的同时，更是显著提升了其与基体间的结合强度，从而提供了一种力学性能和隔热性能优异的铈掺杂钛酸钇陶瓷热障涂层材料。本发明在保证高温相稳定性及低热导率的基础上，提高了热障涂层与基体间的结合强度，该热障涂层材料可适用于航空涡轮发动机高温热障涂层的备选材料，并具有成本较低、工艺简单、易于控制、适合工业化量产的优点。
