Thermal spray coating is a surface treatment method where metal, ceramic, or carbide-based materials are applied to industrial components to protect them against wear, corrosion, and extreme conditions. It is widely used in industries where durability and surface performance are critical.

🔧 How Does Thermal Spray Work?

This method involves heating the coating material—often in the form of powder, wire, or rod—then spraying it onto a surface using high-energy equipment. Key application techniques include:

• Plasma Spray

• HVOF (High Velocity Oxy-Fuel)

• Electric Arc Spray

• Flame Spray

✅ Key Advantages of Thermal Spray Coatings:

• Excellent wear resistance

• Superior corrosion protection

• High-temperature resistance

• Enhanced surface hardness

• Extended maintenance intervals and service life

🏭 Common Industries Using Thermal Spray:

• Plastic Industry: Screws, barrels, molds

• Petrochemical Industry: Valves, piston rods

• Steel Industry: Work rolls, guide rolls

• Paper Industry: Dryer cylinders

• Aerospace & Defense: Turbine blades, engine parts

• Food Industry: Hygienic, non-stick surfaces

📌 Conclusion:

Thermal spray coating is a vital surface protection technology in modern industrial processes. It significantly extends part life, increases system efficiency, and reduces long-term operational costs.
