surface heat treatment
表面热处理
通过对钢件表面的加热、冷却而改变表层力学性能的金属热处理工艺。表面淬火是表面热处理的主要内容,其目的是获得高硬度的表面层和有利的内应力分布,以提高工件的耐磨性能和抗疲劳性能。
对工件表面进行强化的金属热处理工艺。它不改变零件心部的组织和性能 。广泛用于既要求表层具有高的耐磨性、抗疲劳强度和较大的冲击载荷,又要求整体具有良好的塑性和韧性的零件,如曲轴、凸轮轴、传动齿轮等。表面热处理分为表面淬火和化学热处理两大类。
Surface heat treamtne is by heating the surface of the steel, cooling and changing the surface mechanical properties of meta heat treatment process. Surface hardening is the main content of the surface heat treatment.Its objective is to obtain a high hardness of the surface layer and favorable stress distribution, in order to improve the wear resistance and fatigue properties of the workpiece. 
It is metal heat treatment process,to enhance work piece surface. It does not change the organization and performance of the work piece heart section.. It is  widely used in work pices , both surface requires a high wear resistance, fatigue strength and a larger impact load, but also requires a whole has good ductility and toughness, such as crankshafts, camshafts, transmission gears.
Surface heat treatment is divided into two categories: surface hardening and chemical treatment
