HVOF Supersonic Flame Spraying
HVOF supersonic flame spraying technology utilizes high-pressure oxygen combined with fuel (either gaseous fuel or aviation kerosene) to create a high-temperature, high-pressure, and high-speed gas flow through a specialized spray gun. This process propels powder particles delivered by the feeding system into the gun at supersonic speeds, where they are sprayed onto the workpiece surface. The result is a dense, uniform coating with low oxide content—perfect for functional applications in environments requiring exceptional wear and corrosion resistance. Since our company introduced HVOF technology in 2006, we have spent years thoroughly integrating and refining the process, while also developing innovative improvements of our own. As a result, we’ve not only preserved all the outstanding performance characteristics of the original foreign HVOF technology but have also achieved significant advancements, such as miniaturizing the equipment and enabling remote, real-time control. This has made it possible to carry out on-site construction directly inside furnaces, expanding its versatility across a wide range of demanding applications—including wear and corrosion-resistant environments found in waste-to-energy plants, biomass power plants, and other thermal power facilities.
