Thermal spray coatings are a group of processes that use combustion of gases or electrical energy to melt feedstock material in wire, powder, or rod form. The melted material is atomized and propelled to a prepared surface where the material immediately freezes and builds up to create a coating. Our thermal spray coatings are extremely versatile and able to create coatings out of almost an endless number of materials. The technology is used in several industries to provide engineered coated surfaces for improving the components performance.


A Fisher Barton proprietary process, FluxFuse minimizes distortion and warping of components found in typical open air fusing, while providing consistent, uniform fusing conditions for adhering thermal spray wear coatings to the component base material.

Superior fusing of a wear coating results in a much stronger coating bond and, ultimately, increased wear component performance and durability. Combining Fisher Barton’s patented MARBAIN® base material with FluxFuse combines the best of the materials and coatings worlds, offering a world of new opportunities for longer life and improved performance.

A TST proprietary post coating heat treatment done in controlled atmosphere to promote coating diffusion into the coated component to create a metallurgical bond and promote diffusion within the coating almost eliminate coating porosity. The FUSIONbonded coating with its tenacious metallurgical bond can withstand high impact, and the high-density coating provides enhanced wear and corrosion resistance.

Flame Spray

Flame Spray

Is an oxyfuel process in where feedstock material in powder, wire, or rod form is feed into the flame, melted, and carried by the flame and air jets to the surface being coated. Molten particles immediately solidify upon contacting the surface. The process has relatively low gas and particle velocities which can result in coatings higher in porosity and lower in bond strength. The process is economical and can be used in the spray and fuse process where the coating is heat treated after deposition to achieve a strong metallurgical bond and greatly reduce coating porosity.

HVOF, High Velocity Oxyfuel

HVOF, High Velocity Oxyfuel

Uses a fuel gas ( such as hydrogen, propane, or propylene) or liquid (such as kerosene) and oxygen to create a combustion jet. The combustion takes place internally at very high chamber pressures, exiting through a small diameter barrel to generate a supersonic gas jet. Feedstock powder is injected into the jet is heated and accelerated to very high velocities. The process results in dense, well bonded coatings.

Plasma Spray

Plasma Spray

This coating technology uses a high temperature ionized gas, (a gas plasma) that is produced withing the plasma gun. The gas is typically a mixture of argon-hydrogen or argon-helium and it is ionized between a tungsten cathode and copper anode utilizing a dc arc. Core temperatures within the plasma are the highest of all the thermal spray processes, 11,000-27,000oF. These temperatures are higher than any material melting point so many different materials can be melted and turned into coatings.
