为了提高钢铁零件的耐腐性、疲劳强度及某些特殊性能(如抗腐蚀性等),采用了多种表面硬化方法,其中之一就是渗氮法。除了气体渗氮与液体渗氮外,近年来,离子渗氮或称之为辉光离子氮化在热处理领域中占据特别引人注目的地位。离子渗氮有其与众不同的特点,例如,由于离子轰击、阴极溅射等物理过程的作用,影响着渗层的形成、气相的活化、吸附和扩散等基本过程。因而使离子渗氮除具有一般渗氮的特点外,又突出地表现在“质量好、效率高、省能量、无公害”等独特的优
In order to improve the corrosion resistance of steel parts, fatigue strength and some special properties (such as corrosion resistance, etc.), using a variety of surface hardening methods, one of which is the nitriding method. In addition to gas nitriding and liquid nitriding, in recent years, ion nitriding or glow-ion nitriding has taken a particularly prominent position in the field of heat treatment. Ion nitriding has its own unique characteristics. For example, due to the effects of physical processes such as ion bombardment and sputtering, the basic processes such as the formation of the infiltration layer, activation of the gas phase, adsorption and diffusion, etc. are affected. Therefore, in addition to the general characteristics of ion nitriding nitriding, but also prominently in the “good quality, high efficiency, energy saving, pollution-free,” and so unique
