【摘要】 对38CrMoAl进行气体多元共渗处理,共渗后材料表面形成了以氮化物为主的具有一定厚度的渗层,导致其表面硬度、耐磨性的提高。通过X射线衍射对渗层的相结构进行分析,并对渗层的显微硬度、摩擦系数、组织形貌等参数的研究,选择出合理的气体多元共渗工艺。更多还原

【Abstract】 The surface of 38CrMoAl steel can form the nitride-layer with enough thickness after treated by gas muti-elements penetrating , its surface microhardness and tribological property were improved greatly. By researching the parameters of 38CrMoAl steel which include layer structure、 microhardness、 phrase structure、 friction coefficient, we found the suitable process of muti-elements penetrating.更多还原
