High-entropy boride coating as well as preparation method and application thereof
The invention belongs to the technical field of high-entropy coatings, and particularly relates to a high-entropy boride coating and a preparation method and application thereof. According to the invention, through high entropy, the coating has a unique disordered crystal structure of metal sublattices and shows a remarkable effect on enhancing oxidation resistance, and meanwhile, the high-entropy ceramic has multiple components and can form a multi-component oxide after ablation, so that further diffusion of oxidation and ablation is prevented, and the service life of the material is prolonged. The high-entropy boride coating provided by the invention provides possibility for thermal protection of the hypersonic flight vehicle.
本发明属于高熵涂层技术领域，具体涉及一种高熵硼化物涂层及其制备方法和应用。本发明通过高熵化，使得涂层具有独特的金属亚晶格的无序性晶体结构，对增强抗氧化性表现出显著的效果，同时，高熵陶瓷具有多组元，能够在烧蚀后形成多元氧化物，阻止了氧化和烧蚀进一步扩散，延长了材料的使用寿命。本发明提供的高熵硼化物涂层为超高声速飞行器的热防护提供了可能。
