Thermal spray coating is a process that uses electrical energy or consumable flame to melt various types of materials, and then propel this molten metal to the surface of the substrate. For propelling this molten metal compressed air can be used. These thermal spray coatings used for adding a high-quality and high-performance surface coating for covering a variety of equipment and devices. These materials can be in the form of a rod, zinc wire, or powder.
Thermal spray coating technology is so versatile that it can be used for thin layers of coatings as well as thick overlays. This technology is heavily used in all types of industrial fields for upgrading and diversification, as well as improving substrates performance, and development of substrates with new functions.
We offers optimal and effective thermal spraying methods developed with many years of experience in thermal spray technology, including the selection of thermal spraying materials, methods, and spraying substrates, while considering every angle, such as application and required functionality.
Types Of Thermal Spray Coatings
- Combustion flame spray: The flame will be generated via oxygen which has been combined with fuel, and this will melt the mixture. The combustion flame spray process is popular for low-intensity applications due to its low cost.
- Electric arc spray: This spraying method utilizes an arc spray gun that is created between two wires which are electrically conductive and the heat produced by an electric arc is used for melting the material. Melting will occur at the point where the wires connect.
- Plasma spray: Plasma spraying makes use of the plasma torch as the main tool for heating and spraying the coating.
- HVOF (High-velocity oxy-fuel): HVOF gun is a process that makes use of a torch that allows the flame to spread whenever the nozzle is used.
- Cold spray: The materials used for coating are self-fluxing (i.e., they contain elements that react with oxygen or oxides to form low-density oxides that float to the surface, thus improving density, bonding, etc.
