Benefits Application & materials Process details
Combustion spraying is a thermal spray coating process used to apply relatively inexpensive coatings that typically contain high levels of oxides and porosity together, with the option of achieving a rough surface finish.
In the combustion spraying process, a gas stream produced by the chemical reaction between oxygen and a combustion fuel heats a consumable propelling it onto a substrate to form a surface coating.
As the surface technology specialist in combustion spraying, Bodycote provides an array of spray coating materials to suit your specific needs. Backed by a customer-driven service, our facilities process a wide variety of component sizes to exacting standards with reliable, repeatable results.
Combustion spray coatings offer the following benefits:
- Corrosion protection;
- Wear resistance;
- Clearance control – abrasives and abradables;
- Heat and oxidation resistance;
- Temperature management; and
- Electrical resistivity and conductivity.
Application & materials
Typical applications include;
- Pump shafts/journals
- Seal areas
Metallics, ceramics, abradables
Combustion spraying offers a cost effective alternative for applying metallic and ceramic coatings in a less demanding environment.
The process relies on the chemical reaction between oxygen and a fuel of combustion to produce a heat source. The heat source creates a gas stream with a temperature in excess of 3,000°C with correctly balanced conditions between oxygen and acetylene. A consumable, usually a powder or wire, is heated and propelled onto a substrate to form a surface coating.
