Method for preparing carbon/carbon composite material high-temperature oxidation-resistant coating through in-situ reaction
The invention discloses a method for preparing a carbon/carbon composite material high-temperature oxidation-resistant coating through an in-situ reaction, and belongs to the technical field of material preparation. The method comprises the following steps: designing the composition of raw materials, mixing and ball-milling powder, drying, cleaning a carbon/carbon composite material substrate, and preparing the MAX-phase-containing high-temperature anti-oxidation coating through an ultra-high-speed laser cladding method in-situ reaction, so as to prepare the carbon/carbon composite material high-temperature anti-oxidation coating. According to the method, raw material powder is adopted, and an ultra-high-speed laser cladding technology is used for carrying out in-situ reaction on the surface of the carbon/carbon composite material to form an interface MAX phase layer. By means of the toughness of the MAX phase, the problems of cracking and stripping of the coating at high temperature are solved, meanwhile, the matrix carbon participates in the in-situ reaction of the surface, the coating and the matrix are chemically combined, and the binding force of the coating and the matrix is enhanced.
本发明公开了一种原位反应制备炭/炭复合材料高温抗氧化涂层的方法，属于材料制备技术领域。其方法包括原材料组成设计、粉末混合球磨、干燥、炭/炭复合材料基底清洗和超高速激光熔覆法原位反应制备含有MAX相高温抗氧化涂层，制得炭/炭复合材料高温抗氧化涂层。本发明采用原材料粉末利用超高速激光熔覆技术对炭/炭复合材料表面原位反应形成界面MAX相层。借助MAX相本身的韧性，克服了涂层在高温下开裂、剥落的问题，同时，基体炭参与表面的原位反应，涂层与基体呈化学结合，增强了涂层与基体的结合力。
