TD Coating

Thermal Diffusion Extreme Carbide System (TD Coating) is a superior adhesion process which successfully applies a layer of vanadium carbide coating to metal adding long term, uniform and resilient anti-corrosion protection primarily for dies (forming, stamping and piercing) and extrusion tooling.  
TD is the number one requested coating at Surface Heat Treat and Coating. It performs exceptionally well on tool steels such as AISI D-2, AISI A-2, and AISI H-13. 
At Surface Heat Treat and Coatings our treatment process controls thickness of this coating ensuring uniformity across the section (adding only 4 to 8 µm) thereby not compromising dimensions of a tool, die or part.  
If you are looking for optimum performance and long term wear on all metal part, tooling and forming applications than make the investment and give us a call at 905-6640-1666.

Properties of Thermal Diffusion Coatings

Thermal diffusion coatings cover the surface with the carbides, nitrides, or carbonitrides as well as other thin hard coatings processes such as CVD and PVD. The hardness of carbides is very high. Since thermal diffusion coatings are produced by a diffusion process and substrate has contribution in coating formation, the bonding strength and adhesion of these kinds of coatings to the substrate is extremely high in comparison with other coatings methods. Therefore, in metal forming operations such as stamping and forming, where galling is often observed as a surface damage, superior adhesion characteristics of thermal diffusion coatings are potentially good choice. The hardness of vanadium carbide is very high and in some cases it is received 3500 VHN hardness. According to Archard equation the wear resistance of vanadium carbide coated samples is reducing because of high hardness.

Arcor Nitriding

The benefits of Arcor® or Ferritic Nitrocarburizing surface treatment are many and include exceptional resistance to wear, seizure, scuffing, fatigue and corrosion. This non-toxic economical process is carried out at low temperatures mitigating part distortion and can be applied to most steels and cast iron. In most cases part surface wear and corrosion properties improve by 200%-1000% subsequent to treatment.

  • Resists Wear

  • Resists Seizure

  • Corrosion Resistant

  • Decorative Black

  • Quick Turnaround

Case Hardening Carburization

Considered one of the best case hardening heat treatment providers in North America, Surface Heat Treat and Coatings offers a cost effective fast turnaround solutions for surface hardening and improved part or component wear resistance. Similar to our Nitriding process (nitrogen infusion), salt pot carburizing increases strength by infusing carbon into the steel surface creating a case while retaining a lesser hardness in the core. Case depth or diffusion is process and steel dependent and can exceed .050” if required. This process is terrific for most carbon steel applications and is typically used for gears, pinions, wear plates and die forms.

  • Resists Wear

  • Increased Toughness

  • Longer Component Life

  • Vacuum Normalized

  • Clean Finished Parts
