0 前言 在众多的热处理技术中,渗碳与渗氮处理技术作为提高耐磨性和抗疲劳强度的方法被广泛应用在汽车、产业机械的主要零件上,面向21世纪,目前对制造业在地球环境对策、节省能源、再生性、安全、品质等方面提出了更高一级的要求,同样,对其中的热处理也有着向更新一代的渗碳及渗氮技术发展的要求。例如,现在渗碳技术由气体渗碳向真空渗碳,从发生气到直接渗碳,从开放型设备到密闭型设备,一直在改变。但是,另一方面也伴随着处理温度渐渐升高,气氛控制变成间接控制等问题。在考虑下一代热处理设备时必须解决这些问题,但这些问题的
0 Preface Among the many heat treatment technologies, carburizing and nitriding technologies are widely used as the main components of automobiles and industrial machinery as a method to improve the wear resistance and fatigue strength. In the 21st century, Environmental measures, energy conservation, renewable, safety, quality and so put forward a higher level of requirements, the same, for which the heat treatment also has a new generation of carburizing and nitriding technology development requirements. For example, carburizing technology has now been changing from carburizing carburizing to vacuum carburizing, from generating gas to direct carburizing, from open equipment to hermetic equipment. However, on the other hand, problems such as a gradual increase in the treatment temperature and an indirect control of the atmosphere control are also encountered. These issues must be addressed when considering the next generation of heat treatment equipment, but these are the issues
