Anti-ablation ceramic coating containing polymer derived nanocarbon and preparation method of anti-ablation ceramic coating
The invention relates to an anti-ablation ceramic coating of polymer-derived nanocarbon and a preparation method of the anti-ablation ceramic coating. The anti-ablation ceramic coating is structurally characterized in that a polymer conversion ceramic method is adopted to prepare multiphase ceramic containing a uniformly dispersed nanocarbon material, and a plasma spraying method is adopted to prepare the anti-ablation ceramic coating containing the polymer-derived nanocarbon. Due to the fact that the organic carbon source containing unsaturated bonds is added into the precursor, multiphase ceramic rich in nanocarbon is generated in situ in the inorganic transformation process through the front-end design of a polymer molecular structure, uniform distribution of the nanocarbon material in the ceramic is achieved, and the heat-conducting property of the prepared ceramic coating is improved; heat accumulation of the composite material in an ablation environment due to pneumatic heating is reduced, efficient heat dissipation is achieved, and the anti-ablation protection service life is prolonged.
本发明涉及一种聚合物衍生纳米碳的抗烧蚀陶瓷涂层及其制备方法，其结构特征在于采用聚合物转化陶瓷法制备复相陶瓷中含有均匀分散的纳米碳材料，通过等离子喷涂法制备含聚合物衍生纳米碳的抗烧蚀陶瓷涂层。由于在前驱体中加入含不饱和键的有机碳源，通过聚合物分子结构的前端设计使其在无机化转变过程中原位生成富含纳米碳的复相陶瓷，实现纳米碳材料在陶瓷中的均匀分布，提高制备陶瓷涂层的导热性能，降低复合材料在烧蚀环境中由于气动加热造成的热量累积，实现高效散热提高抗烧蚀防护寿命。
