HVOF Corrosion Resistant Coatings
A high velocity combustive spray for exceptional performance
- Combustion-based system delivers extremely low coating porosity
- Creates high coating densities without reduction in bond strength
- High spray velocity adheres more persistently to substrates
- Deposes coatings with a high coefficient of hardness
- Pressure and heat combine for greater surface smoothness
- Usable for both ceramic and metallic coatings up to 12mm (1/2") thick
High Velocity Oxy-Fuel (HVOF) coatings fight corrosion by enhancing the surface consistency, hardness and bond strength of many coating types, including tungsten carbide, chrome carbide, nickel alloys, cobalt alloys and various carbon and stainless steels. The HVOF process centers around a spray head that mixes oxygen, a combustible fuel (kerosene, acetylene, propylene and hydrogen) and a powdered friction-reducing coating material. A jetlike nozzle delivers coatings at temperatures of 5-6000o F at velocities beyond 7000 feet per second.
This process results in a coating with an extraordinarily high coefficient of adhesion, commonly exceeding bond strengths of 12,000 psi. HVOF allows coatings to maintain their corrosion resistant properties in high temperature environments, or in applications which must endure mechanical stress from high levels of friction.
HVOF is particularly useful for restoration of worn components to original tolerance specifications. Coatings can be applied up to 1/2" thick without significant compromise to bond strength, corrosion protection or friction resistance.
