Vanadium Carbide Coating (TDH)

Vanadium Carbide Coating (TDH)

IBC’s TDH coating is performed using a hot process (1800-1900 °F) that combines carbon from the tool surface with vanadium to grow a vanadium carbide layer that is metallurgically bonded to the substrate. This method of thermally diffusing a vanadium carbide layer onto the surface creates an incredible bond far stronger than any deposited coating, resulting in longer tool life.

Advantages:

  • Metallurgical bond of VC with substrate
  • Substrate is hardened to optimum hardness
  • Can coat deep inside holes and pockets

Technical Data:

  • Phase content of the coating: VC
  • Hardness of VC layer: 3300 - 3500 HV
  • Hardness of base metal: 700 - 800 HV
  • Layer thickness: 0.0004'' - 0.0006''
  • Very low coefficient of friction
  • No Coarsening of the base metal
