1.导言盐浴渗碳由于其高的质量水准、广泛的应用可能性、以及高度的经济性而获得了越来越重要的意义。对于高负荷零件:为达到可重现的、一定的强度性能,而经常必须在盐浴中进行渗碳。为此,可从大量例子中举数例如下: 对于在孔的下部区域内具有临界疲劳断裂区的五档变速箱主轴,盐浴渗碳者的疲劳强度试验得出十分有利的数值。在实际中,情况亦复如此(气体渗碳者,在试运行中出现断裂;盐浴渗碳者不出现断裂)。对其它传动件,同样也只有通过盐浴渗碳来达到所要求的齿根强度。盐浴渗碳试样的旋转弯曲疲劳强度试验
1. Introduction Salt bath carburization is gaining more and more importance because of its high quality level, wide range of possibilities and high economy. For high-load parts: In order to achieve reproducible, certain strength properties, often carburizing must be carried out in a salt bath. For this purpose, the following examples can be cited from a number of examples: Fatigue strength tests for salt-carburized persons yield very favorable values for five-speed transmission spindles with critical fatigue fracture zones in the lower region of the bore. In practice, the same is true (gas carburizing, fracture during commissioning; salt bath carburizing does not appear broken). For other drive parts, the same root strength is also achieved only with salt bath carburizing. Rotational Bending Fatigue Strength Test of Salt Bath Carburizing
