Cementation is the process in which carbonation occurs at a certain temperature, in case of nitro-cementation with carbon and nitrogen. Subsequent turbidity of the cemented or nitro-cemented component results in formation of a high hardness layer while maintaining the high toughness and plasticity of the core of the material. The thickness of the layer is, if desired, in the range from a few tenths of a millimetre to several millimetres. Only low-carbon steels are used to produce subsequent cemented or nitro-cured components. Typical components include gears, toothed shafts and pinions, larger rolling bearings, screws, etc., with high wear and tear resistance and resistance to contact fatigue.
This process is carried out in semi-automatic multipurpose chamber furnaces IPSEN with controlled carbon potential in the cementation atmosphere and in the case of nitro-cementation with the addition of ammonia.
