1967年,西德克罗克纳离子有限公司首次将离子氮化法用于工业生产,随后在各国迅速发展。六十年代末,我国便开始了离子氮化的研究,发展也很快。在设备方面,完成了强电流辉光放电的研究,由调压器电源发展为有限流电阻的可控硅电源,进一步发展为取消限流电阻,有快速电子开关的电源,能显著节约能源。1977年以来,300A、500A大功率离子氮化炉相继投产。同时,离子氮化炉所需的各种检测技术也取得了不少试验研究成果。关于离子氮化机理的研究,提出了“碰撞—裂解”模型,引起了国内外同行的兴趣。离子氮化的主要优点是能对化合物层及
In 1967, Croton Ion Co., Ltd. for the first time in the ion nitriding method for industrial production, followed by rapid development in various countries. In the late 1960s, China started its research on ion nitriding and developed rapidly. In terms of equipment, the research on strong current glow discharge has been completed. The power supply developed from regulator to thyristor with limited current resistance further developed to eliminate the current limiting resistor and power supply with fast electronic switch, which can save energy significantly. Since 1977, 300A, 500A high-power ion nitriding furnace have been put into operation. At the same time, the ion nitriding furnace required a variety of testing techniques have also made a lot of experimental research results. As for the research on the mechanism of ion nitriding, the “collision-cracking” model has been put forward, arousing the interest of domestic and foreign counterparts. The main advantage of ion nitriding is the ability to compound layers and layers
