一、引言多年来的实践证明,盐浴渗碳能成功地满足在高应力和磨损服役条件下零件的使用要求。通过试验比较,证明盐浴渗碳比气体渗碳具有更高的耐磨和耐疲劳性能。因此,对如图1(略)中所示的一些要求较高的零件,大都采用盐浴渗碳;而承受高应力的赛车和自行车零件,为获得最佳性能,通常也采用盐浴渗碳工艺。 I. Introduction The practice over the years has proved that salt bath carburization can successfully meet the requirements for the use of parts under high stress and wear service conditions. Through the comparison of experiments, salt bath carburization proved to be more resistant to wear and fatigue than gas carburization. Therefore, salt-carburizing is most commonly applied to some of the more demanding parts shown in Figure 1, while car and bicycle parts subject to high stress are often treated with salt bath carburizing for optimum performance Process.
