SILNITRONTIN

CVD, SILNITRON TIN  coating based on multilayers of titanium nitride and titanium carbide with Si contribution

SILNITRON TIN is a CVD coating based on ceramic compounds of Ti and Si, thus obtaining temperatures close to 1000 ºC. Such temperature facilitates the coating's diffusion creating an anchorage with the substrate and thereby getting adhered within its structure. Adherence is greater to that of the PVD coatings without shear stresses.

Flubetech has developed RP CVD (reactive particles) so as to obtain the reactants in situ and with perfect chemical homogeneity and a thickness uniformity in every working zone.

SILNITRON TIN is specially designed for gravers and coining presses, which in general terms means for conforming material. The CVD-coated pieces must allow dimensional tolerances of 1/10000. After the coating step, the quenching and tempering step must be carried out flawlessly since it could cost distortions.


Benefits of the coating SILNITRON TIN

  • High hardness and resistance to wear.
  • The coating is exceedingly-well fixed to the substrate, specially under shear stresses.
  • Avoids hot and cold micro-solders.
  • Facilitates the plate's sliding, specially for stainless steels.
  • Excellent superficial finish that minimizes the deformation efforts.
  • Minimizes the required, lubricant quantity.
  • Ease to eliminate the remains of the laminated material that might have adhered onto the coating's surface.
