一、前言 提高渗碳温度能够使渗碳速度急剧的增加,这已经 是大家所熟悉的事。但是在以前有很多研究数据都说明 了:渗碳温度超过一定范围时,除了加速渗碳速度以外, 还会使零件过热、表面层碳浓度过高、零件的机械性能 降低。因此,以前一般的说法是渗碳温度最好在930℃ 以下。这? First, the preface Increasing the carburizing temperature can make carburizing the rapid increase, which is already familiar to everyone. However, in the past a lot of research data shows that: carburizing temperature exceeds a certain range, in addition to accelerating the carburizing speed, but also make the parts overheating, the surface carbon concentration is too high, the mechanical properties of parts to reduce. Therefore, the general rule of thumb is that the carburization temperature is preferably below 930 ° C. This?
