已有大量著作专门研究渗氮层的形成及其高硬度的本质【1—7等】。一些研究者认为,渗氮层之所以硬度高,是由于析出了合金元素的弥散氮化物,并堵塞了滑移面之故
A large number of books have been devoted to the formation of nitrided layers and the nature of their high hardness [1-7]. Some researchers believe that the reason why the nitriding layer is high in hardness is due to precipitation of alloying elements of the dispersed nitride and block the slip surface so
