一、前言研究合金元素对化学热处理表面层影响的部门,为了研究合金元素对氧氮化的影响而进行了各种试验,现将他们的实验结果报告如下: 我们熟悉的氧氮化法是在氧化后用过热蒸汽进行氧化处理的一种复合处理方法或者是在NH_3气中添加5%水蒸汽的Rogalski法。然而本文所论述的氧氮化法是日本汽车 I. INTRODUCTION Departments that study the effect of alloying elements on the surface layer of chemical heat treatment have carried out various experiments in order to study the effect of alloying elements on oxynitridation. Their experimental results are reported as follows: The oxynitride method we are familiar with Oxidation with superheated steam for oxidation treatment of a complex treatment or NH_3 gas to add 5% water vapor Rogalski method. However, the oxynitride method discussed in this article is a Japanese car
