HVOF coatings have been used for over forty years across many industrial sectors to create very hard, dense coatings with low compressive strengths. HVOF coatings have been specifically developed to increase the service life of new metallic components as well as repair parts that have suffered from corrosion, erosion or wear. ACI Ltd operates fully automated spray booths to ensure a high-quality finish, proven to exceed component life well beyond that of the original specification.
The HVOF process utilises a fuelgas and oxygen torch that propels a carefully mixed amount of powder onto the substrate at high velocities. The molten powder then sets and solidifies in a fraction of a second to form the specified coating.
Example HVOF sprays include Tungsten Carbide, Tungsten Cobalt, Nickel Chrome and Chrome Carbide.
In addition to High Velocity Oxy Fuel (HVOF) coatings, ACI Ltd offers a range of over 200 thermal coatings.
