PLASMA SPRAY

In plasma spraying process, the material to be deposited (feedstock) — typically as a powder, sometimes as a liquid, suspension or wire — is introduced into the plasma jet, emanating from a plasma torch. In the jet, where the temperature is about of 10,000 K, the material is melted and propelled towards component’s surface. There, the molten droplets flatten, rapidly solidify and form a deposit. Commonly, the deposits remain adherent to the substrate as coatings.

HVOF

High Velocity Oxygen Fuel (HVOF) is one of the most commonly used spray coating to improve or restore a component’s surface properties or dimensions, thus extending equipment life by significantly increasing erosion and wear resistance, and corrosion protection.

POWDER & WIRE FLAME SPRAY

With the combustion wire spray process, the wire spray material is melted in a gaseous oxygen-fuel flame. The wire is fed continually into the fuel gas-oxygen flame, where it is melted and atomized by the addition of compressed air that also directs the melted onto the substrate.

WIRE ARC SPRAY

Wire arc spray is a form of thermal spraying where two consumable metal wires are fed independently into the spray gun. These wires are then fed and an arc is generated between them. The heat from this arc melts the incoming wire, which is then entrained in an air jet from the gun.
