What is Thermal Spray Powder?
Thermal spray powder is an alloy, ceramic or plastic material that can be thermally sprayed onto a surface. The particle size distribution is a factor, as are the type of thermal spray process and atomization method.
Flame, arc, plasma or HVOF systems apply metals, ceramics and carbides to surfaces with copper powder for corrosion protection, abrasion and wear resistance, heat dissipation, hard-chrome replacement, electrical / thermal conductivity, radiation shielding etc.
What is a Thermal Spray Coating?
Thermal spray powder is a type of coating material that can be sprayed onto a surface. It is made up of a mixture of powdered metal wire or ceramic or metal powder that is heated and melted and then sprayed onto the surface.
Thermal spraying is a type of coating process in which the "feedstock" (coating precursor) is heated using an electrical (plasma or arc) or chemical means (combustion flame). These coatings are used for surface enhancement and surface remanufacturing.
Generally, a thermal spray coating is resistant to wear, erosion, cavitation and corrosion. It also can provide electrical conductivity or insulation, lubricity, high or low friction and other desirable surface properties.
The most common coating materials are cermets, hard alloys and oxide ceramics. These are typically sprayed at various thicknesses. These coatings have a high level of resistance to wear, and are used in applications like bearings and gears. Abradable coatings are also often sprayed for jet engines and gas turbines.
What is a Thermal Spray Material?
Thermal spray powder is a coating material that comes in the form of wire or powder, which is heated and sprayed onto a surface. This gives the coating material a variety of properties including corrosion protection, environmental protection, lubricity, wear resistance and electrical/thermal conductivity.
There are a variety of thermal spraying processes, but they all involve the projection of small softened particles onto a cleaned and prepared surface. These particles then adhere to the surface using combined thermal and kinetic energy, forming a cohesive coating of successive layers.

The earliest thermal spraying process, flame spraying, involves an oxy-acetylene flame that heats and melts the coating feedstock (powder). When the melted powder is sprayed, it can be propelled onto the substrate via compressed air or a jet of gas.
What is a Thermal Spray Process?
Thermal spray is a broad family of surface coating processes with 316l powder that applies metallized, ceramic or carbide coatings to a variety of substrates to increase their physical properties. These coatings are used to protect and extend the life of a wide range of components operating in harsh environments.
In each of these processes, a molten or semi-molten feedstock material is propelled through a stream of gas or compressed air. As the particles impact and collide with a clean, prepared substrate, they flatten and'splat' onto the surface and each other, producing a cohesive coating of successive layers.
Cold spray does not heat the feedstock material to high temperatures, which allows for deoxygenation to occur over a much shorter time than in the plasma or flame thermal spray processes. This prevents oxygen from building up on the sprayed coating particles, which is an important factor in avoiding corrosion. In addition, this method does not create a heat affected zone, which can cause damage to the underlying substrate.

What is a Thermal Spray Application?
Thermal spray coatings are used for a wide range of applications that improve wear resistance, corrosion resistance, traction, and to reclaim surfaces. These coatings are applied to many different substrates, such as metals, alloys, ceramics, cermets, and carbides.
For this reason, thermal spray is an extremely versatile technique that can be used for a wide variety of purposes. This makes it an ideal solution for companies in a wide range of industries like for stainless steel powder price.
The process of thermal spraying involves the heating and melting of a coating precursor (also known as a feedstock) to produce an adhesive bond between it and the surface being sprayed. This can be accomplished by electrical means (plasma or arc), or by chemical means (combustion flame).
For wire flame spray, a combination of gas fuel and oxygen is ignited to create a flame that heats and melts the coating feedstock. This is then sprayed onto the work piece. The rate of spray is determined by the diameter of the wire feedstock, which influences how quickly the material will be sprayed.
