Nitrocarburising of low alloyed case hardening steels applying three different temperatures

摘要

Nitriding is one of the most important processes among surface technologies. The purpose of this process is to produce a wear resistant layer on the surface of components, to meet the complex requirements. Ferritic nitrocarburising was carried out at three different temperatures (520, 570 and 620°C) and with five different process times, to study the effects on process parameters . The experiments proved that in case of ferritic nitrocarburising, it is possible to produce larger diffusion zone during the same time. If the temperature is higher than the ironnitrogen eutectoid temperature, the diffusion is deeper, but we should consider the softening of the core.
