一、测定渗碳层深度的原理和方法合金渗碳钢18Cr2Ni4WA属于马氏体钢,在渗碳处理以后,即使在随炉缓慢冷却的情况下,仍然得到不平衡组织,所以渗碳层深度的测定就显得十分困难。为了寻找一种方法,既能够明显地显示出渗碳层边界,又能够准确地测定渗碳层深度,我们依据S曲线,当合金元素确定以后,一定的含碳量在一定的淬火温度下,其Ms点基本上是一定的,Ms点是随含 First, the determination of the carburizing layer depth principle and method Alloy carburizing steel 18Cr2Ni4WA belongs to the martensitic steel, carburizing treatment, even in the case of slow cooling with the furnace, still get unbalanced organization, so carburizing layer depth Measurement is very difficult. In order to find a way, not only can clearly show carburizing layer boundary, but also can accurately measure the depth of carburizing layer, we based on the S curve, when alloying elements are determined, a certain amount of carbon content in a certain quenching temperature, The Ms point is basically certain, Ms point is with
