前言真空沉积镀层能有效地防止机械零部件的磨损,烧蚀,腐蚀和氧化。由于真空沉积的镀层是一个原子一个原子地生长的,所以可以把真空沉积技术看作是原子过程。详细的组织特性最为重要;为了确定整个界面区的结合特性、形核和生长特性,就需要从原子级别到宏观级别的组织特性资料。耐磨或防腐镀层的效能主要取决于选用的镀覆技术。摩擦和腐蚀特性主要受镀层附着力,内聚力和组织形态的影响。附着力直接与表面预处理方法和形成的界面类型有关,但组织形态(形核与生长)则直接受表面光洁度、清洁度和蒸发物流量的影响。上
Introduction Vacuum deposition coating can effectively prevent the mechanical parts wear, ablation, corrosion and oxidation. Because the vacuum deposition of the growth of atoms is an atom, so the vacuum deposition technology can be regarded as atomic processes. Detailed tissue characteristics are paramount; in order to determine the binding properties, nucleation, and growth properties of the entire interface area, data on tissue characteristics from the atomic level to the macro level are required. The performance of a wear-resistant or anti-corrosion coating depends mainly on the choice of plating technique. Friction and corrosion properties are mainly affected by coating adhesion, cohesion and morphology. Adhesion is directly related to the method of surface preparation and the type of interface formed, but the morphology (nucleation and growth) is directly affected by the surface finish, cleanliness and the flow of the vaporizer. on
