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.

Vacuum Heat Treating

With over 5000 lbs of capacity and 5 foot long furnaces, Surface Heat Treat and Coatings can handle almost any sized heat treating job and is has one of the best Heat Treat service teams in Ontario, Canada. Vacuum heat treatment is one of the best ways to heat treat parts. Since parts are heat treated in a vacuum environment, the parts are kept clean, uncontaminated and without any oxidization. Uniformity and dimensions are better maintained.

  • Bright Clean Work

  • No Decarburization

  • Less Distortion

  • Controlled Heating

  • Controlled Quenching

Arcor Nitriding

The benefits of nitriding are many, but the most important one is wear and corrosion resistance. After nitriding , the surface of the tool will have wear and corrosion resistance properties that are 200%-1000% greater than the original material. It is also an excellent alternative to hard chrome for environmental reasons as hexavalent chromium is not used at any step in the Arcor process. Nitriding surface treatments have one of the longest track records of success of any case hardening technologies. Our treatments are used throughout the world to enhance the wear and tear resistance of lower alloy steels and stainless steels.

Case Hardening

Case hardening infuses carbon into the surface of steel, which makes it harder and more wear resistant. This application is popular due to the cost effectiveness and quick turn around time of the process. With case hardening, the typical tools that use this application are gears, pinion shafts, wear plates and die forms. Surface Heat Treat and Coatings does a high volume of case hardening on a daily basis and are considered one of the best metal heat treating companies for case hardening in North America.
