CARBO-IN LOW PRESSURE THERMOCHEMICAL TREATMENTS

CARBO-IN® LOW PRESSURE CASE-HARDENING

This is a controlled carbon diffusion-process, which takes place at a pressure ranging between 5 and 9 mbars, in the absence of oxygen, at a temperature between 930 ° C and 1,050 ° C. This is continued with the tempering carried out in high-pressure gas.

ENVIRONMENTAL ADVANTAGES OF CARBO-IN LOW PRESSURE THERMOCHEMICAL TREATMENTS:

  • Absence of smoke and fumes arising from the use of oil during the temper process
  • Reduction of energy consumption
  • Total elimination of waste to be disposed of

ENVIRONMENTAL ADVANTAGES OF CARBO-IN LOW PRESSURE THERMOCHEMICAL TREATMENTS:

  • Drastic reduction of temper deformation
  • Customization of the process in relation to the issues of each individual component
  • Increased resistance to fatigue and wear thanks to the absence of intergranular oxidation
  • High reproducibility and ease of control over the process
  • Homogeneity of the case in all of sections of the component , even on complex pieces
  • Uniformity of treatment in the case of dead holes or through holes
  • Extreme cleanliness of the post treatment piece
  • Absence of any oxidation of the surfaces
  • Residual austenite less than 5%
  • Uniformity of case depth inside of the charge of ± 0.05 mm
  • Absence of cortical bainite

PRODUCTIVE ADVANTAGES OF CARBO-IN LOW PRESSURE THERMOCHEMICAL TREATMENTS:

  • Reduction of lead times
  • Management of small batches
  • High productivity
  • Extreme flexibility
  • Reduced cycle time

ECONOMIC ADVANTAGES OF CARBO-IN LOW PRESSURE THERMOCHEMICAL TREATMENTS:

  • Glossy and brilliant aesthetic appearance
  • Reduction of machining allowances
  • Elimination of certain machining phases following the treatment
  • Elimination of straightened pieces
  • Total absence of carbon and dry oil residues
  • Elimination of abrasive blasting, tumbling, peening, final cleaning, etc…
  • Guaranteed absence of “residual dirt”
