Oerlikon Metco, Switzerland (AMT) Amtag High-Velocity Oxygen Fuel (HVOF) Thermal Spray Cell

High-Velocity Oxygen Fuel (HVOF) coating is a thermal spray coating process used to improve or restore a components surfaces (properties or geometry). This surface engineering technique better enables life extension of equipment by increasing erosion and wear resistance and corrosion protection.  

HVOF spraying was developed in the 1980s and is a subset of thermal spraying. HVOF spraying works by mixing fluid fuel and oxygen, which is fed into a combustion chamber and ignited. Able to deposit many coatings.

The resultant gas has an extremely high temperature and pressure, which is ejected through a nozzle at supersonic speeds. To the high velocity gas stream, powder is injected, which partially melts. The stream of hot gas and powder is directed towards the surface to be coated.
The resulting dense coating has low porosity and high bond strength, providing many benefits such as corrosion resistance, wear protection, low friction., high temperature, oxidation resistance, electrical insulation, repair & insulation.

High velocity oxy-fuel (HVOF) spraying is primarily used to apply high quality coatings of Carbides and Cermets such as WC/Co and WC/Co/Cr.
Coating thickness is usually in the range 0.1-2 mm.
Characteristic features of HVOF sprayed coatings include their low level of porosity at about 1-2vol% and low oxide content in the range 1-2wt%.
The bond strength often exceeds 80MPa.
These coatings can be used across a spectrum of engineering and manufacturing applications to enhance the surface properties of components.
This allows preparation of cost effective, high performance parts made from low cost or lightweight materials with a functional surface.

Commonly deposited coating materials include:
• Cermets (e.g. WC/Co, WC/Co/Cr, Cr 3C 2/NiCr, NiCrSiBC)
• Ceramics (e.g. Cr 2O 3, Al 2O 3, ZrO 2)
• Metal alloys (e.g. steels, nickel, chromium and cobalt alloys including NiCrSiB and MCrAlYs)
• Pure metals (e.g. Ni, Cu, Al, Mo, Ti)
• Polymers (e.g. polyester, nylon)
• Composites (e.g. Ni-graphite)

HVOF spraying can produce coatings for:
• Wear protection
• Low friction surfaces
• Corrosion protection
• High temperature oxidation resistance
• Electrical insulation
• Repair and restoration of damaged components
