摘　　要：用外加热方式在管状反应室中对高速钢试样进行离子氮化，对氮化层的厚度变化、表面硬度及冲击韧性随Ｈ２／Ｎ２、渗氮温度及时间的变化进行研究。High speed steel samples were ion nitrided in a tube reactor with an auxiliary heating furnace. The change of nitriding layer thickness,surface hardness and impact strength of the sample with H 2/N 2 ratio,temperature and time were studied.Comparison between samples nitrided in reactors with and without auxiliary heating was made.
