一、前言渗氮层一般分为两部分:化合物层和扩散层。化合物层呈白色,一般很薄,难以被一般化学试剂腐蚀。通常用电子显微镜观察其组织的精细结构。采用双喷射制膜技术难于控制试样的部位。本试验采用自制的离子减薄机,成功地制备出渗氮层表面化合物的薄膜试样,清晰地观察了化合物层的精细结构。二、试验方法试验材料是超高强度马氏体时效钢,经固溶、时效处理后进行离子氮化。氮化温度
First, the preface nitriding layer is generally divided into two parts: compound layer and diffusion layer. Compound layer is white, generally thin, it is difficult to corrosion by the general chemical reagents. The fine structure of the tissue is usually observed with an electron microscope. The use of dual-jet film technology is difficult to control the sample site. In this experiment, a thin film sample of a nitrided layer surface compound was successfully prepared by a self-made ion-reducing machine, and the fine structure of the compound layer was clearly observed. Second, the test method The test material is ultra-high-strength martensitic aging steel, the solution after aging treatment of ion nitriding. Nitriding temperature
