一、离子氮化组织控制离子氮化最主要的优点就是通过改变离子氮化气氛、压力、电参数、温度等来控制氮化表面化合物层的结构和扩散层组织,从而获得具有较高的疲劳强度、耐磨性和抗蚀性能的韧性硬化层,氮化层通常由化合物层和扩散层两部分组成。其组织控制问题,从其获得的方法而言也是一个重要的工艺问题。 1.单相γ’化合物层的控制西德用900℃氨分解气进行离子氮化,对各种合金结构钢均能获得Y’单相化合物
First, the ion nitriding organization The main advantage of ion nitriding is to control the nitriding surface compound layer structure and diffusion layer structure by changing the ion nitriding atmosphere, pressure, electrical parameters, temperature, etc., so as to obtain high fatigue Strength, wear resistance and corrosion resistance of the ductile hardened layer, the nitride layer is usually composed of two layers of the compound layer and the diffusion layer. Its organizational control is also an important process issue in terms of the methods it obtains. 1. Single-phase γ ’compound layer control West Germany with 900 ° C ammonia decomposition gas ion nitriding, for all kinds of alloy steel can get Y’ single-phase compound
