LOW-TEMPERATURE CARBURIZING METHOD USING CARBON POTENTIAL CONTROL

摘要

The present invention is to provide a low-temperature carburizing method for effectively preventing soot generated on the final product of a low-temperature carburizing process. The low-temperature carburizing method according to the present invention comprises a step (a) of performing pretreatment on a target metal, a step (b) of introducing the target metal into a reaction chamber and raising the temperature to a set temperature, and a step (c) of forming a vacuum atmosphere in the reaction chamber and supplying a reaction gas containing at least hydrocarbon gas to perform carburization. In the step (c), the hydrocarbon gas is supplied below a preset reference threshold considering relationship between a plurality of carburizing processes during carburization.;COPYRIGHT KIPO 2020
