Thermal Spray Carbide Coating Services | Wear Resistant Coating Solutions

TSE provides tungsten carbide thermal spray coating by HP-HVOF process to hydropower plant's components to protect them from abrasive, erosion, sliding wear, corrosion, and oxidation under high temperatures. The thermal spray carbide coating process creates an enormous amount of kinetic energy in the powder or melted tungsten carbide particles. When these vibrant particles hit the substrate, their speed low down to zero and they soak their kinetic energy, which drives them to connect instantly to the structure. We have the ultimate HP/HVOF system , HIPOJET 2700M, JP-5000 with robotics for metallic and carbide powder coating. HVOF refers to High Velocity Oxy-Fuel which is the most appreciated thermal spray coating solution by numerous industrial units in India. It is most commonly used to repair machine parts and offers durable and highly resistant surface coatings. Moreover, it best suits the requirements of OEM ( Original Equipment Manufacturer ) dimensions or rigid tolerance.

Tungsten carbide (WC-Co-Cr) coatings applied via High-Pressure HVOF provide extreme microhardness (>1200 HV), making them the industry standard for combating sliding abrasion, slurry erosion, and fretting wear.

HVOF tungsten carbide is 2x to 3x more wear-resistant than electroplated hard chrome, achieves bond strengths >70 MPa, has zero microcracking, and is completely environmentally friendly (no hexavalent chromium).

Typical parts include hydro turbine runner blades, guide vanes, pump impellers, boiler feed pump shafts, mud rotor shafts, wire drawing capstans, and extruder screws.

Yes, using diamond grinding wheels and superfinishing belts, tungsten carbide coatings can be ground to mirror finishes with surface roughness values of Ra 0.05 µm or finer.

WC-Co-Cr is suitable for temperatures up to 500°C. For higher operating temperatures (up to 850°C), we recommend Chromium Carbide (Cr3C2-NiCr) formulations.
