What is Thermal Spray Technology?
Thermal spray technology involves different metallizing processes and techniques of applying a protective coating to the surface of parts and equipment exposed to harsh operating environments. Various materials including ceramics and metals are used in thermal spray technology and they can be applied to almost any type of metal. These coatings are ideal for rebuilding worn parts and for providing protection against high temperatures, corrosion, wear, abrasion and chemicals.
Thermal spray coating companies work with a wide range of industries including power generation, steel, aerospace and paper. Thermal spray metalizing technology is highly versatile and is a cost-effective way to increase part life, save on costly repairs, and prevent loss of productivity resulting from equipment downtime.

How Are Thermal Spray Coatings Applied?
Materials including metals and ceramics are used to create a protective coating. They can appear in a variety of feed stock including powder and wire depending on the material and application process.
Most Metalizing Thermal Spray processes involve similar technologies: a spray gun, spray materials and a carrier gas. To apply the coating, the material, either in wire or powder form, is transformed to a semi-molten state. Particles are then accelerated towards the surface through various gas velocity. As the micro particles hit the surface, the particles solidify to form the coating.
For thermal spray coating materials that cannot withstand heat, Cold Spraying is an alternative that utilizes powder mixed with a carrier gas to form coatings on a substrate.
Metalizing Thermal Spray Processes Offer Countless Benefits
Applying a metallizing protective surface to a part substrate providing increased service life and low maintenance. Because of longevity achieved, metallizing is a cost-effective process.
What Metallizing Processes Are Included in Thermal Spray Technology?
Thermal spray technology covers several different processes, each offering their own benefits. All can be used to rebuild worn parts or on new components to create a protective layer, but the methods used to apply the coatings produce different results.
Plasma Arc Spraying
Plasma electric arc spraying involves introducing powder into a heated plasma gas stream to create a high-density coating using a large array of materials. It provides a full range of protection and is commonly used for a large cross-section of industrial applications. Plasma electric arc spraying is a versatile solution for materials, including ceramics, where components require high temperature resistance, extreme wear resistance and inert chemical resistance.
High Velocity Processes (HVOF)
High velocity processes (HVOF) involve combining fuel and oxygen in a combustion chamber. The spray materials are then introduced to the powder and fed through a nozzle where it is accelerated onto the workpiece surface. HVOF creates a consistent, hard-particle surface with low porosity to provide high resistance against wear, corrosion and abrasion.
Electric Wire Arc Spraying
Electric wire arc spraying is an economically efficient process that uses an arc to produce heat and provides one of the fastest coating rates. Instead of using an external heat source, two electrically opposed charged wires are fed together, creating an arc strike at the intersection and melting the wire. Compressed gas is then used to propel and spray the molten metal onto the part surface. The capability to produce thick build-up and higher bond strengths makes this thermal spray process ideal for dimensional repair. Because of its cost-efficiency, electric wire arc spraying is also commonly used for high-volume application of coatings.
Cold Spraying
Cold spraying is a non-heated, high kinetic process that requires minimal surface preparation and provides high density oxide-free coatings. The low gas preheat temperatures and low nozzle exit temperatures significantly reduce the occurrence of high-temperature oxidation and other concerns associated with other thermal spray technology processes. The low temperatures make cold spraying suitable for heat-sensitive materials.
