Oct 07, 2014 · Tungsten Carbide (WC) Thin Films. Thin films of tungsten carbide have wide technological appliions as wear resistant and protective coatings on a variety of surfaces such as cemented carbide tools, steel, copper, and copper alloys. For normal steel, copper, and copper alloys, a coating of WC–Co has been found to be suitable.
The high temperature Fluoropolymer is applied over the tungsten carbide and cured to form a permanent bond. While the tungsten carbide provides superior wear resistance, the Fluoropolymer remains in the "valleys" to provide release. This coating provides not only release and wear resistance, but a level of corrosion resistance as well.

These coatings are applied using high velocity equipment and generally will have the best bonding properties to the base materials. Common Carbides include: Tungsten carbide/stainless steel, Tungsten carbide/hastelloy, Tungsten carbide/nickel, Chrome carbide/nickel, Chrome carbide/nichrome and more. Metal/Alloy Use:
Tungsten carbide coating is done through a process known as HighVelocity Oxygen Fuel spraying (HVOF). This tungsten carbide coating process involves the use of combustive thermal spray at high velocity to develop exceptional wear and corrosion resistance. It is by far the most preferred method of coating owing to the many benefits it presents.

Tungsten carbide (chemical formula: WC) is a chemical compound (specifically, a carbide) containing equal parts of tungsten and carbon atoms. In its most basic form, tungsten carbide is a fine gray powder, but it can be pressed and formed into shapes through a process called sintering for use in industrial machinery, cutting tools, abrasives, armorpiercing rounds, other tools and instruments
plating. Typical tungsten carbide coatings are applied in an hour or two, versus 24 hours or more required for hard chrome plating. Furthermore, unlike hard chrome coatings, HVOF tungsten carbide coatings do not undergo hydrogen embrittlement, so the time and cost required for embrittlementrelief treatment is eliminated.
In 1926, Krupp, a German company, developed carbide, a very hard mixture of sintered carbides of various heavy metals, especially tungsten carbide, used for cutting edges and dies. This new material revolutionized metalremoval or "chipcutting" in manufacturing. In the 1950s, carbide was used in all machining processes except for sawing.
2003. A. Tungsten carbide is also deposited by PVD and electrospark deposition. The PVDdeposited WC is not a good substitute for hard chrome it''s used more as a solid lubricant, having a high C content. Electrospark deposition is a welding process carried out at room temperature.
