Tungsten carbide coating is a thermal spray layer of tungsten carbide particles in a metal binder, applied by HVOF to give a steel part a very hard, dense surface that resists abrasion, erosion and corrosion. Ultraweld Coat applies it in Pune to valve trim, pump parts and rolls.
Ultraweld Coat the best Tungsten Carbide Coating Service Providers in Pune. As top Tungsten Carbide Coating Service Providers, we are offering advanced coatings services which will produce high quality performance in your industrial operations. By limiting the temperature of the pipeline, valves, and studs for approximately an hour, flange guards are specialized items designed to prevent external fires in hydrocarbon fluid pipe lines and valves and to safeguard personnel escaping from a potential fire area to a safe position.
Provides reliable protection against aggressive corrosive elements and sour environments.
Extremely hard surfaces that protect parts from severe abrasive wear and erosion.
High-density coatings that form an impermeable seal against fluid penetration.
Optimized coating structure to prevent delamination and ensure long service life.
Exceptional adhesion properties, keeping coatings intact under high impact loads.
As a Pune’s top Tungsten Carbide Coating Service Providers, our coatings are corrosion resistance, high wear resistance, low porosity, low residual stress, and strong bond strength. By regulating the tungsten carbide particles’ volume in relation to cobalt and their grain size, HVOF tungsten carbide coatings offer the particular characteristics required for a certain application.
For your application, Ultraweld Coat can select the optimal powdered feedstock. As a top Tungsten Carbide Coating Service Providers, we provide HVOF thermal spray rooms with ample space for a variety of parts, turning capabilities, and equipment kinds.

| Grade | Strength | Typical use |
|---|---|---|
| Tungsten carbide cobalt | Highest wear resistance | Dry or mildly corrosive abrasion and sliding wear |
| Tungsten carbide cobalt chrome | Wear resistance with better corrosion resistance | Wet service: valve trim, pump sleeves, hydraulic rods |
| Tungsten carbide nickel chrome | Best corrosion resistance of the three | Corrosive process fluids and seawater |
Tungsten carbide coatings are used up to moderate temperatures. For hot service, chromium carbide nickel chrome is the usual substitute.
HVOF tungsten carbide is harder and denser than hard chrome plating, wears more slowly and avoids the hexavalent chromium used in plating baths. It is now the common choice for rods, plungers and rolls that were once chrome plated.
The coating is too hard for conventional cutting tools, so it is finished with diamond wheels in our grinding shop, and sealing faces are lapped. The thickness is set so that the specified coating remains after grinding.
Tungsten carbide coating is a highly durable surface treatment applied to various substrates to improve wear resistance, hardness, and corrosion resistance. It consists of tungsten carbide particles embedded in a metallic binder, often applied using thermal spray techniques.
Tungsten carbide can be applied by HVOF to most metals, including carbon and alloy steels, stainless steel and nickel-based superalloys. The surface is grit blasted first. Suitability also depends on the shape of the part, because the spray needs line-of-sight access to the surface.
Tungsten carbide coatings are known for their superior hardness and wear resistance compared to many other coatings like chromium carbide or ceramic coatings. They are particularly effective in applications involving severe abrasion and high temperatures.
Yes. A worn or damaged tungsten carbide coating can usually be stripped and the part re-coated and re-ground, provided the base metal is in good condition. Re-coating restores the original dimensions and extends the service life of the component.
