Cold Coating

Cold Vanadium Carbide coating - TDC was developed in 2007 and is used in most demanding applications - forming stainless steel, high strength alloys, galvanized steel, aluminum and magnesium die casting, medical and many more.

The cold TD coating has the same or better performance than the regular Hot TD process and has the following advantages:

- No deformation of the components

- Unlimited amount of re-coatings and repairs  

The mechanical properties of the substrate and the cold coating (toughness, hardness and ductility) can be additionally enhanced through the thermal diffused sub layer. The dense and thick structure that is created will decrease the plastic deformation of the tool under the effect of the concentrated load.

• Technical data of the TDC coating:

-Deposition temperature         : 500º F - 600º F

-Thickness of the coating        : typically 6 microns (0.0002”)

-Depth of the thermal

 diffused layer                        : 25- 50 microns (.002”)

-Hardness                              : typically 3500-3800 HV 020

-Coefficient of friction               : less than 0.08  (Steel on steel conditions)
