高速钢刀具的氧氮化处理,是一种较新的化学热处理方法。它是在等于或稍低于高速钢回火温度下,使成品高速钢刀具表面在氨和水的混合气氛的作用下,同时渗入氧和氮的一种工艺过程,是蒸汽氧化和表面渗氮工艺的复合。经过氧氮化处理过的高速钢刀具表面呈深兰色,无脆性,有较高的硬度(HV_5900以上),同时有较高的抗粘附性和耐腐蚀性,从而提高了刀具的寿命和防锈能力。实验证明,经氧氮化处理过的高速钢刀具大约提高寿命1～1.5倍以上,个别类型的刀具可提高几倍～十几倍。这种处理的另一些优点是操作简便,工作环境清洁,不会产生废气和有害气体。
Oxynitriding of HSS tools is a relatively new chemical heat treatment method. It is equal to or slightly lower than the high-speed steel tempering temperature, the finished high-speed steel tool surface in a mixture of ammonia and water under the action of infiltration of oxygen and nitrogen at the same time a process that is steam oxidation and surface nitriding Technology complex. After oxygenated nitrided high-speed steel cutter surface dark blue, no brittleness, high hardness (HV_5900 above), while a high resistance to adhesion and corrosion resistance, thereby enhancing the life of the tool and Anti-rust ability. Experiments show that the oxygen-nitrided high-speed steel cutting tool to increase the life of about 1 to 1.5 times more than individual types of tools can increase several times to ten times. Other advantages of this treatment are easy handling, clean working environment, no exhaust gases and no harmful gases.
