通过对６种常用渗碳材料在９３０℃下进行渗碳试验，建立了表面碳浓度控制模型，渗碳时间延长时，表面碳浓度按抛物线规律上升。钢种、碳势不同，表面碳浓度也不同，研究了表面碳浓度与炉气碳势达到的渗碳平衡时间。
Through the carburizing tests on 6 commonly used carburized materials at 930 ℃, a surface carbon concentration control model was established. When the carburizing time was extended, the surface carbon concentration increased according to the law of parabola. With different carbon potential and different surface carbon concentrations, the surface carbon concentration and the carburizing equilibrium time reached by the furnace carbon potential were studied.
