HVOF Coating

The High Velocity Oxygen Fuel (HVOF) process was developed to produce high quality metal, carbide and various specialty coatings. A complete line of powders are available, which are specifically engineered for application with the HVOF System. The commercialization of this coating technology now affords industry the ability to get unique coating properties and extend the range of applications which previously could only be performed by proprietary coating processes.

A&A Company, Inc. offers this state of the art coating system as an adjunct to it’s existing Plasma and Metallizing coating capabilities.

HVOF Coatings exhibit superior characteristics with respect to different applications:

RESTORATION OF DIMENSION AND CORROSION RESISTANCE

• High Density;
• Excellent Bond Strength (weld-like); and
• Superior Corrosion Resistance.

WEAR RESISTANCE

• High Velocity of Particles;
• Minimal Decarbonization of Particles;
• Minimal Porosity;
• Excellent Interparticle Cohesion; and
• Very Hard (HV 1000+).

HIGH TEMPERATURE COATINGS – WEAR/OXIDATION-CORROSION:

• High Density – Minimize hot gas infusion; and
• Minimal Decarbonization – Improves hot wear resistance.
