离子沉积技术在本杂志上已有详细介绍。该技术能够解决热处理不能解决的问题,即能使固态下互不溶的膜材和基材界面之间形成过渡层(可互溶金属更可促进过渡层形成)。为了区别热扩散所形成的过渡层,称之为“伪扩散”型的过渡层。它可以将膜材与基材的物理性能差异所引起的应力(如热应力等)分散在一个较宽的过渡层中,避免了应力过分集中, Ion deposition technology has been described in detail in this magazine. The technology can solve the heat treatment can not solve the problem that can make the solid state of insoluble film and substrate interface between the transition layer (miscible metal can promote the transition layer formation). In order to distinguish the transitional layer formed by thermal diffusion, it is called the “pseudo diffusion” transitional layer. It can be the physical properties of the film and the substrate caused by differences in stress (such as thermal stress, etc.) dispersed in a wider transition layer, to avoid excessive stress concentration,
