前言等离子喷涂是现代表面强化的一项新技术,已普遍用于各个工业部门,并取得了很好的经济效益。由于等离子喷涂包含复杂的物理和化学反应,且这种反应极其迅速,这就不可避免的在涂层中产生孔隙及其它缺陷。为了满足对涂层质量高要求,除测定涂层的机械性能和物理性能外,必须对涂层的任一局部区域进行组织结构分析,以了解等离子涂层的形成特点,探索涂层与基体牢固结合的物理化学现象的本质。
Preface Plasma spraying is a new surface enhanced modern technology, has been widely used in various industrial sectors, and achieved good economic benefits. Since plasma spraying involves complex physical and chemical reactions and the reaction is extremely rapid, it is inevitable that voids and other defects are created in the coating. In order to meet the high coating quality requirements, in addition to measuring the mechanical properties and physical properties of the coating, the microstructure of any part of the coating must be analyzed in order to understand the formation characteristics of the plasma coating, to explore the coating and the substrate firm The nature of combined physical and chemical phenomena.
