In this paper, studies on the decomposition of Vietnamese gas in a carburizing media are presented. The research results show the formation of a carburizing media when using a mixture of gas, nitrogen and CO2. In addition, the paper presents the research results on the influence of the gas/CO2 ratio, gas retention time on the formation of a carbon in permeable medium. Experimental results with a Gas/CO2 ratio of 2 and a retention time of 18 minutes show the formation of a carburizing layer in 20CrMo steel; The effective permeable depth layer is 680µm.
