| 摘 要： | 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。

| Abstract: | arburising experiments were conducted for six sorts of carburising materials in com-mon use at temperature 930℃,and established the control model of surface carbon concentration. The usual form is Cp=Cs=C0- Along with the extending of carburising time,the surface carbon concentration was going up in the parabolic law. When the carburising material,the carbon potential changes,the two factors C_0 and K are changed,the surfaee car-bon concentration is affected. In addition,the carburising equilibrium time (the time of surface carbon concentration) was studied.The carburising equilibrium time had mainly something to do with carburising material and carbon potential. |
