LOW-PRESSURE CARBURISING METHOD

摘要

The invention relates to a low-pressure carburising method comprising alternating low-pressure enrichment steps and diffusion steps in the presenc e of a neutral gas. During the enrichment steps, an enriching gas and neutral gas mixture is used, the proportion of the neutral gas being between 5 and 5 0 % by volume of the enriching gas. The enriching gas can be, for example, acetylene (C2H2).
