Flame spray is a process that uses an oxy-fuel flame to melt wires and in some cases powders or ceramic rods. The molten material is then atomised with compressed air to create a spray stream that applies the coating onto the surface being sprayed.
Our flame spray equipment is designed for those who demand the best in thermal spraying solutions – installed with features that ensure a superior finish with minimal hassle. Most systems are manually operated but it is possible to semi-automate or fully-automate the process if required.
Anti-corrosion coatings are typically applied with oxy-propane systems. Engineering coatings are typically applied with oxy-acetylene systems. Where propane is not available, oxy-acetylene systems can apply anti-corrosion coatings.
Metallisation has a full range of wire, powder and ceramic rod flame spray systems in hand-held or automated versions. See the full range below:
Flame spray is a process used in surface coating applications where a material, typically a metal or ceramic, is melted by a flame and then propelled onto a surface to form a coating.
This technique involves heating the material to its melting point using a combustible gas, such as acetylene or propane, and then spraying it onto the desired surface using compressed air. The molten particles solidify upon impact, creating a durable and protective coating.
Flame spraying is similar to paint spraying. Once the system is connected up, the sprayer operates a valve to start the gases flowing and lights the gas stream. A trigger is then used to start/stop the wire feed into the flame, depositing the coating in a manner akin to spray painting.
Flame spraying is a technique used to improve the durability, corrosion resistance, and overall performance of various materials.
Aluminium, ceramic, low carbon steel and nickel-based materials are some of the commonly used materials for flame spraying.
Most metals can have an aluminium coating applied by using the flame spray process. This can be for aesthetics, anti-corrosion, conductivity or many other reasons.
Zinc can be applied to most substrates by the flame spray process. This is often to provide galvanic protection of the substrate but may be for a number of other reasons.
