通过彩色金相的方法显示了离子渗氮层及固体渗硼组织．结果表明彩色金相不仅可使不同深度的渗层组织清晰显现，还能够使渗层各区域的各相组织显示出来．简单讨论了各相着色原理．
Through the color metallographic method shows the ion nitriding layer and solid boronizing structure. The results show that the colored metallography can not only clearly show the different depth of the disseminated tissue, but also enable the various phases of the disseminated tissue to be displayed. A brief discussion of the principle of each phase shading.
