一、辉光离子氮化辉光离子氮化是一种提高金属零件表面硬度的热处理新工艺,它是通过辉光放电的形式使氮渗入金属的。辉光离子氮化的原理,是在一个真空容器内通入0.1～10托的氨或氮、氢混合气体,以真空容器当阳极,被处理工件为阴极,接入一个几百伏至一千五百伏的可调直流电压,使气体电离,电子移向阳极,氮、氢离子移向阴极,并以每秒10~(11)米的速度撞击工件为工件表面所吸收和向工件内层扩散,从而形成氮化层。整个处理过程中,工件被一层稳定的辉光所包覆。离子氮化与其他形式的氮化比较,具有氮化周期短、工件变形小、表面化合层的组织结构和厚度容易控制、能量消耗少、无公害等优
First, glow ion nitriding glow Ion nitriding is a heat treatment to improve the hardness of the metal parts of the new technology, which is through the glow discharge of nitrogen into the metal. Glow ion nitriding principle is in a vacuum vessel into the 0.1 ~ 10 Torr of ammonia or nitrogen, hydrogen gas mixture to a vacuum vessel as the anode, the workpiece is treated as the cathode, access a few hundred volts to a thousand Five hundred volts of adjustable DC voltage, the gas ionization, the electrons move to the anode, nitrogen, hydrogen ions move to the cathode and the speed of 10 to (11) meters per second impact the workpiece as the workpiece surface absorption and the inner layer Diffused to form a nitride layer. The entire process, the workpiece is covered by a layer of stable glow. Compared with other forms of nitriding, ion nitriding has the advantages of short nitriding period, small deformation of the workpiece, easy control of the structure and thickness of the surface compound layer, less energy consumption and pollution-freeness
