表面渗碳层的碳浓度剖面,象其表面含碳量一样,对合金钢渗碳零件的使用性能影响很大。当零件有相应的碳分布的剖面时能够达到最大的耐磨性、弯曲疲劳强度和接触疲劳强度。用多段渗碳法在可变碳势和恒温扩渗条件下或在改变温度的条件下能够得到不同的剖面。本文提出一个合金钢多段渗碳的计算模型,该模型能够在碳势可控的放热型气氛或
Carburizing the surface of the carbon concentration profile, as the surface of the same carbon content, the use of carburizing steel alloy parts greatly affect the performance. When the part has a corresponding distribution of carbon profiles to achieve maximum wear resistance, bending fatigue strength and contact fatigue strength. With multi-stage carburizing method in the variable carbon potential and constant temperature infiltration conditions or under the conditions of changing temperature can get different profiles. This paper presents a calculation model of multi-section carburizing alloy steel, the model can control the carbon potential of the exothermic atmosphere or
