Thermal Spray

Electric-Arc Spray Coating

Electric-arc spray coating uses two conductive wires to carry electrical charges of opposite polarity. When the two charges meet at the front of the spray device an electrical arc is created and this arc melts the wire. The molten wire is the feedstock material for creating a coating. It has the capability of depositing coatings at very high spray rates. 

Flame Spray Coating

Flame spray coating employs combustion of gases to melt powder, wire or rod material and propel the molten droplets onto a surface to create a coating. Its gas velocities are much slower than HVOF. Flame spraying can create coatings out of a wide range of materials from plastics to oxide ceramics. 

Plasma Spray Coating

Plasma spray is the most versatile of the all the thermal spray processes. Plasma spray coatings can be employed on all materials considered sprayable.

High Velocity Oxy-Fuel Coating (HVOF)

High velocity oxy-fuel coating (HVOF) is a subset of flame spraying. This technology is capable of producing very dense and well adhered coatings in the as-sprayed condition.  



Fisher Barton uses a 6kWTrumpfTruDisk solid state laser, which provides us the opportunity to apply materials to surfaces serving multiple industries.  The laser is primarily used for cladding, heat treating and additive manufacturing, but has a wide range of capabilities and benefits.

Plasma Transferred Arc (PTA)

The Fisher Barton Technology Center operates a Robotic Plasma Transferred Arc(PTA) System.  This PTA System is capable of producing coatings under momentary high temperatures(~25,000 °C) while being shielded by inert gas.  These unique properties allow for the production of high purity, low porosity, coatings.  Combined with robotic motion, this PTA System produces repeatable fusion coating, at a high deposition rate.
