The depth and microhardness distribution of alumetizing layer obtained on different technical conditions were measured. 测定了不同工艺条件下获得的浸渗层深度和浸渗层显微硬度的分布。
By means of regression design, the rela-tional formula between the depth of the thermal damage layer and parameters of technology was found. 采用回归设计方法，通过试验找出齿面变质层深度与各工艺参数间的关系式。
