Ultrahigh-temperature oxidation-resistant ablation-resistant ceramic coating and preparation method thereof
The invention provides an ultrahigh-temperature anti-oxidation ablation-resistant ceramic coating and a preparation method thereof, and relates to the technical field of coating processing. The surface of a substrate is sequentially coated with a metal bonding layer, a ceramic inner layer, a ceramic transition layer and a ceramic outer layer; the thickness of the metal bonding layer ranges from 0.05 mm to 0.20 mm. The thickness of the ceramic inner layer ranges from 0.30 mm to 0.80 mm. The thickness of the ceramic transition layer ranges from 0.05 mm to 0.30 mm. The thickness of the ceramic outer layer ranges from 0.20 mm to 0.80 mm. Raw material powder of the ceramic inner layer, the ceramic transition layer and the ceramic outer layer is densified through the induction plasma spheroidizing technology, then the densified powder is sprayed to a base body through the atmosphere plasma spraying technology, the multi-layer ceramic coating is formed, and therefore the high temperature resistance, the oxidation resistance and the ablation resistance of the tungsten-copper base body material are improved.
本发明提供了一种超高温抗氧化耐烧蚀陶瓷涂层及其制备方法，涉及涂层加工技术领域。本发明是在基体表面依次涂覆金属黏结层、陶瓷内层、陶瓷过渡层和陶瓷外层；所述金属黏结层的厚度为0.05～0.20mm；所述陶瓷内层的厚度为0.30～0.80mm；所述陶瓷过渡层的厚度为0.05～0.30mm；所述陶瓷外层的厚度为0.20～0.80mm。本发明陶瓷内层、陶瓷过渡层以及陶瓷外层的原料粉均是经过感应等离子球化技术进行致密化处理，再利用大气等离子喷涂技术将致密化处理后的粉体喷涂在基体上，形成多层陶瓷涂层，以提高钨铜基体材料的耐高温、抗氧化、耐烧蚀性。
