Supersonic Spraying (High-Velocity Oxygen Fuel, HVOF/HVAF) is an advanced surface treatment technology. It accelerates and heats powder materials in a supersonic combustion gas stream, propelling them to impact the substrate at high velocity to form dense coatings with superior bonding strength. Core equipment includes spray guns, powder feeders, gas control units, cooling systems, and automated platforms. This technology is widely applied in aerospace, energy, and defense industries to enhance component wear resistance, corrosion resistance, and high-temperature performance.

Our Product: Supersonic Spray Gun Barrels  

As critical consumables for supersonic spraying systems, our spray gun barrels and components are engineered for high-performance coating processes with these advantages:  

•Exceptional Durability: Copper alloy construction withstands high-temperature, high-velocity particle erosion, extending service life.  

• Precision Engineering: Optimized internal geometry ensures stable gas flow and uniform powder acceleration for consistent coating quality.  

• Broad Compatibility: Adaptable to mainstream equipment models with customizable solutions.  

• Rapid Replacement: Modular design minimizes downtime and boosts production efficiency.

Application Scenarios:  

• Defense: Ablation-resistant coatings for gun barrels  

• Energy: Thermal barrier coatings for turbine blades  

• Manufacturing: Wear-resistant repair for hydraulic rods

Technology Principle: Supersonic spraying involves axially feeding powder into the flame stream. Particles are heated to molten/semi-molten states and accelerated, producing high-density coatings with exceptional bonding strength.
