能量为几十千到几百千电子伏离子射入材料表面,使表面层的组成与结构发生改变,从而引起材料表面的物理与化学性质的变化,这种材料改性方法有极其重要的应用。如摩擦、润滑性、耐磨损性、表面硬化、抗高温氧化性、耐腐蚀性、催化及附着力改善等。虽然离子注入可改善材料这些性质,但由于经济与技术上的原因,最重要的研究集中在耐磨损性、抗高温氧化性及某些耐蚀性上,而耐磨性的研究以工具上的应用为最多。
The energy is tens to thousands of electron volts ions incident on the surface of the material, the surface layer of the composition and structure of the change, causing the material surface of the physical and chemical properties of the material modification method has an extremely important application . Such as friction, lubricity, wear resistance, surface hardening, high temperature oxidation resistance, corrosion resistance, catalyst and adhesion improvement. Although ion implantation can improve these properties of materials, the most important research focuses on abrasion resistance, high temperature oxidation resistance and some corrosion resistance due to economic and technical reasons, and the research on wear resistance is based on tools The most used.
