Metal powder spray, also known as thermal spraying or metal spraying, is a surface engineering process used to apply metallic coatings to various substrates. The technique involves heating a metal powder to a molten or semi-molten state and then propelling it onto the surface of a substrate using a spray gun or similar apparatus. Once the molten or semi-molten particles come into contact with the substrate, they rapidly solidify, forming a cohesive and adherent coating.
The terms "metal spray powder" and "metal powder spray" are often used interchangeably, but they can refer to slightly different aspects of the same process.
"Metal spray powder" typically refers to the powdered form of the metal used in thermal spraying processes. It is the material that is heated and propelled onto the surface to form a coating, this is also called thermal spray powder.
On the other hand, "metal powder spray" can refer to the entire process of applying the metal powder onto a surface using a thermal spraying technique. This process involves heating the metal powder to a molten or semi-molten state and then spraying it onto the substrate to form a coating.
So, while the terms are closely related and often used interchangeably, "metal spray powder" specifically refers to the material being sprayed, whereas "metal powder spray" encompasses the entire process of applying the metal powder onto a surface.
Metal spray powders (thermal spray powders) are available in various compositions to suit different applications and requirements. They can be made from a wide range of metals, including aluminum, zinc, stainless steel, nickel, and cobalt, among others. These powders are used for purposes such as corrosion protection, wear resistance, thermal insulation, and electrical conductivity in industries like aerospace, automotive, energy, and manufacturing. Oerlikon Metco has an extensive portfolio of powders. Below is an overview of some options. Feel free to reach out for more information or go to MyMetco for more details.

As mentioned, metal powder spray is another word for thermal spraying which is the process of applying the metal powder onto a surface using a thermal spraying technique, we can summarize the key steps:
