HVOF, or High Velocity Oxygen Fuel, is a thermal spray coating process used to apply protective coatings to various surfaces. It involves the combustion of a fuel gas and oxygen, which creates a high-velocity jet that melts and propels powdered materials onto a substrate. This results in a dense and durable coating that enhances wear resistance, corrosion protection, and thermal stability. The HVOF process is commonly used in industries such as aerospace, automotive, and manufacturing. It is particularly effective for coating components like turbine blades, valves, and pumps, helping to extend their lifespan and improve performance in demanding environments.
