一概述氮化是将氮原子渗入工件表面形成富氮硬化层的热处理工艺过程。氮化后的工件表面硬度高、变形小、疲劳强度显著提高、而且能增强耐腐蚀性能,因而在工业上已得到广泛应用。氮化虽然具有很多优点,但是一般需要专用的氮化设备,工艺也 An overview of nitriding is the nitrogen atoms into the surface of the workpiece to form nitrogen-rich hardened layer heat treatment process. After nitriding the workpiece surface hardness, deformation, fatigue strength increased significantly, but also enhance the corrosion resistance, which has been widely used in industry. Although there are many advantages of nitriding, but generally require a dedicated nitriding equipment, technology also
