自从1923年德国A·Fry博士发表著名的钢的渗氮处理论文,提出了专用的铬镍铝渗氮硬化钢以来,这一方法引起了人们的注意,并获得了应用。特别是七十年代以来,渗氮新工艺、新设备、新材料不断涌现,工艺日趋完善。实践证明,渗氮处理具有提高钢铁表面硬度、耐磨性、疲劳强度和耐蚀性等特点;且具有处理温度低,变形小,不需要后处理等优点,在生产中得到广泛应用,大大提高了各种机械零件和工模具的使用寿
Since 1923, Dr. A.Fry of Germany published a famous steel nitriding treatise, and put forward a special chromium-nickel-aluminum nitrided hardened steel, this method has attracted people’s attention and gained application. Especially since the seventies, nitriding new technology, new equipment, new materials continue to emerge, the process is maturing. Practice has proved that nitriding has the characteristics of improving the surface hardness, wear resistance, fatigue strength and corrosion resistance of steel, etc. It also has the advantages of low processing temperature, small deformation, no post-treatment and other advantages. It has been widely used in production and greatly increased A variety of mechanical parts and tooling life
