Nitrocarburizing has acquired increasing
significance especially when the process is combined with steam
oxidation. The result of this heat treatment is a wear resistant
oxidation layer which is similar to hard chrome plating with
comparably good corrosion resistance. A desirable secondary
effect is the black or anthracite colored part surface. This
treatment requires furnaces with a gastight retort. The heating
can take place electrically or with industrial gas burners. The
chamber retort furnace, especially designed for that purpose,
offers all the conditions for an economic heat treatment with
reproducible results:
- high temperature uniformity
- strong gas circulation
- minimized use of process gas
- programmable heat treatment process
- controlled oxidation layer by means of lambda probe
- extremely high cooling rate through rapid indirect cooling
system
This furnace has all the advantages of vertical retort furnaces,
but needs neither pits
nor hoists. It can be charged more easily and can be integrated
into existing AICHELIN chamber furnace lines.
