前言等离子喷涂是一项现代化的表面防护与强化新技术。陶瓷材料的等离子喷涂技术由于其涂层的许多独特性能和工艺复杂性,已成为近年来热喷涂行业研究发展的热门,正在许多高科技部门得以推广。等离子喷涂陶瓷粉末包含复杂的物理、化学反应,且这些反应极其迅速,因此难以避免地会在陶瓷涂层中产生孔隙、裂纹等缺陷。为获得高质量的等离子陶瓷涂层,须对陶瓷涂层的任一局部区域进行 Preface Plasma spraying is a modern surface protection and strengthening of new technologies. Plasma spraying technology of ceramic materials has become a hot research and development of thermal spraying industry in recent years because of its many unique properties and process complexity, and is being promoted in many high-tech sectors. Plasma-sprayed ceramic powders contain complex physical and chemical reactions, and these reactions are extremely rapid, making it difficult to avoid defects such as voids, cracks and the like in ceramic coatings. In order to obtain a high quality plasma ceramic coating, any localized area of ​​the ceramic coating
