一前言 38CrMoAlA钢氮化具有表面硬度高,耐磨性好等优点,它是机械工业中广泛采用的热处理工艺。38CrMoAlA钢经氮化处理后,表面氮化层的硬度是一个不均匀体,其硬度值往往随氮化层深度增加而下降,其下降的程度往往与氮化处理工艺、材料的化学
A preface 38CrMoAlA steel nitriding has the advantages of high surface hardness, good wear resistance, it is widely used in the mechanical industry heat treatment process. The hardness of the surface nitrided layer of 38CrMoAlA steel after nitriding treatment is an inhomogeneous body, its hardness value often decreases with the depth of the nitrided layer, and its degree of decrease is often related to the nitriding process, the chemical
