Thermal barrier coating ceramic material and preparation method and application thereof
The invention belongs to the technical field of coating materials, and particularly relates to a thermal barrier coating ceramic material and a preparation method and application thereof. The invention provides a thermal barrier coating ceramic material. The thermal barrier coating ceramic material comprises the following components in percentage by mole: 94-95% of ZrO2, 0-5% of Y2O3 and 0.5-5.5%of Er2O3. By doping Er2O3 into the yttria-stabilized zirconia material, the intermediate infrared emissivity of the thermal barrier coating ceramic material is improved, the thermal radiation absorption capacity of the thermal barrier coating ceramic material at high temperature is improved, and the thermal conductivity of the thermal barrier coating ceramic material is reduced, so that the thermal shielding performance of the thermal barrier coating ceramic material is improved.
本发明属于涂层材料技术领域，具体涉及一种热障涂层陶瓷材料及其制备方法和应用。本发明提供了一种热障涂层陶瓷材料，按摩尔百分含量计包括以下组分：94～95％ZrO2，0～5％Y2O3，0.5～5.5％Er2O3。本发明通过在氧化钇稳定氧化锆材料中掺杂Er2O3提高了热障涂层陶瓷材料的中红外发射率，改善了热障涂层陶瓷材料高温下的的热辐射吸收能力，降低了热障涂层陶瓷材料的热传导率，从而提高了热障涂层陶瓷材料的热屏蔽性能。
