Preparation method of carbon/carbon composite material high-temperature anti-oxidation coating
The invention discloses a preparation method of a carbon/carbon composite material high-temperature anti-oxidation coating, and belongs to the technical field of material preparation. The preparation method comprises the following steps: taking an MAX phase material as a main raw material; carrying out ball milling and drying; cleaning the carbon/carbon composite material substrate; and preparing the MAX-phase high-temperature anti-oxidation coating by adopting an ultra-high-speed laser cladding method, so as to prepare the carbon/carbon composite material high-temperature anti-oxidation coating. According to the method, MAX-phase powder is used for carrying out anti-oxidation coating treatment on the surface of the carbon/carbon composite material by using an ultra-high-speed laser cladding technology. By means of the toughness of the MAX phase, the problems of cracking and stripping of the coating at high temperature are solved, the binding force of the coating and a matrix is enhanced, and the method is simple in process, short in operation time, high in efficiency and beneficial to large-scale production.
