This paper deals with the kinetics of carbon atoms transfer from gas phase to solid phase in gas carburizing. According to the kinetic equations of the chemical reactions on the solid surface, it is deduced that the carbon transfer quantity from gas phase to solid phase is in direct proportion to the difference of carbon activiries between gas phase and solid phase. Based on what is mentioned above, we set up the kinetic equation of carbon transfer from gas phase to solid phase, discussed the factors which affected the carbon transfer. It was known then that increasing the contents of carbon monoxide and hydrogen in gas phase could qu'icken the carbon transfer. On the other hand, proper oxidants, especially proper water, could quicken the carbon transfer.
