摘要
用等离子喷涂法在不锈钢基体上制备了HfC陶瓷涂层,用X射线衍射分析仪和扫描电镜对所制备的HfC涂层分别进行了组织结构和外表形貌的分析,并对涂层试样进行了烧蚀试验.试验结果表明,可以用等离子喷涂法制备较为致密的HfC涂层,HfC涂层的线烧蚀率为0.019 mm/s.
The HfC coating used for ablation and thermal protection has been developed by plasrna spraying on the stainless steel samples. The microstructure of the powder and the coating of HfC were investigated by means of X-ray diffractometry（XRD） and scanning electron microscopy（SEM）. The ablation test has been made to coaling samples. The experimental results show the compacter HfC coatings can be prepared by plasma spray process and the ablation rate of coating is 0. 019 mm/s.
