渗碳钢兼有高的表面强度和良好的疲劳强度,在机械装备中常用作传递重负荷的齿轮、轴等零件。这些渗碳零件的性能、寿命能否达到设计要求,对热处理工作者来说是个重要问题。以齿轮为例,要求渗碳淬火以后具有耐磨性(齿面)、耐点蚀性、耐剥落性,良好的齿根弯曲疲劳特性和耐冲击性等等,这些特
Carburized steel combines high surface strength and good fatigue strength, commonly used in the mechanical equipment to transmit heavy-duty gears, shafts and other parts. The performance of these carburized parts, life expectancy can meet the design requirements, heat treatment workers is an important issue. Taking gear as an example, it requires carburizing and quenching to have wear resistance (tooth surface), pitting corrosion resistance, spalling resistance, good root bending fatigue resistance and impact resistance, etc.
