摘要
本文在热分解氨的基础上加入氩气进行离子渗氮 ,探讨了加氩的作用机理 ,研究了40Cr、3 5CrMoA、2 5CrMoV及HI3等钢种加氩对离子渗氮的影响。结果表明 :在热分解氨的基础上加入适当比例的氩气 ,有助于氮原子的扩散 ,起到快渗作用 ,增加有效硬化层深度。
In this paper,effect mechanism of Ar-adding is discussed on the basis of dissociated ammonia as gas.The effects of Ar is developed on ionic nitriding for 40Cr、35CrMoA、25Cr2MoV and H13 steels。The results show that it is helpful for enhancing N diffusion and osmosis through ionic nitridng with appropriate atmospheres Ar on the basis of dissociated ammonia helps,effective hardness layer is increased,and glow thickness is thinned which benefit to ionic nitriding of complex components.
