Abstract
A reduction in the duration of carbon impregnation during gas carburizing is normally achieved either by increasing the temperature of the process or creating rapid circulation of the atmosphere within the furnace. Both of these methods have their specific drawbacks and it is difficult to accomplish them in practice. A simpler and cheaper method is carbon impregnation without controlled atmospheres containing only CO and H2. Here alongside a reduction in the duration of the process it is possible to use slow atmosphere velocities within the charge which simplifies the construction of the carburizing furnace.
