The technology is used for near-surface carburisation at temperatures below 500c. Due to low process temperatures carbon atoms remain in solid interstitial solution. Chromium carbide precipitation does not occur and thus corrosion protection persists. The solid solution of carbonin the fcc lattice produces internal conpressive stresses, increasing hardness values to 1200HV. The obtainable diffusion depth of carbon depends on process time. Industrial suppliers offer diffusion depths of 20 to 40 m.
