| Abstract: | Rapid carburizing process of steel 20CrMnTi by increasing furnace pressure is studied and its mechanism is analysed in this paper. Carbon potential in gas atmosphere can be raised by increasing furnace pressure, physics absorption speed of active carbon atom on workpiece can be raised, and in the meantime diffusion velocity in workpiece can be raised. Thus, this process can enhance the carburizing speed and shorten the carburizing time and improve oroductivitv. |
