What is Thermal Spray?
Thermal spray coating is a general term for methods in which coating materials in powder or wire form are melted by an electric arc, flame, or plasma, and the molten particles are sprayed onto the substrate material with the help of a spraying gas, allowing them to adhere.
By applying the coating, many beneficial applications can be achieved simultaneously, such as restoring worn parts to their original dimensions, protecting against general corrosion, and increasing wear resistance.
How We Help Your Business Thrive
At Senkron Surface Technologies, we understand that every business has unique needs. That’s why our processes are tailored to your industry and operational requirements. With our high-performance coating solutions that enhance wear resistance, we ensure production continuity, extend equipment lifespan, and boost your competitive edge. By combining the right technology with the right strategy, we take each step toward success—together.
Plasma Spray Coating
Plasma spray coating is based on the principle of turning gases (such as argon, helium, hydrogen) ionized by an electric arc into plasma and spraying the coating powder onto the surface by injecting it into this high-temperature plasma flow. The temperature of the plasma jet can reach up to 15,000 °C, allowing ceramic powders that are difficult to melt to be processed easily.
Flame Spray Coating
Flame spray is based on the principle of melting the coating powder or wire-form material in a flame created by a mixture of flammable gas (usually acetylene or propane) and oxygen and spraying it onto the surface. This method is preferred on large surfaces and in applications with low/medium performance expectations due to its low equipment cost and practical use.
HVOF (High Velocity Oxy-Fuel)
HVOF coating is based on the principle that combustion gases, which are formed by burning a mixture of fuel gas (propane, hydrogen or kerosene) and oxygen under high pressure, are passed through a nozzle at supersonic speed. The coating powder is injected into this high-speed gas flow and hits the surface at a speed of 800–1000 m/s. In this way, a mechanically very dense, high surface density and strong adhesion coating is applied to the part.
