This is a useful process for applying relatively inexpensive coatings that typically contain high levels of oxides and porosity together with the option of achieving a rough surface finish.
The process relies on the chemical reaction between oxygen and a fuel of combustion to produce a heat source.
This heat source creates a gas stream with a temperature in excess of 3,000°C with correctly balanced conditions between oxygen and acetylene.
Among others, the process is typically used for applying bond coat materials or materials for corrosion resistance applications.
Due to the small dimensions of the equipment used, this technique is very useful for on-site applications (boiler, infrastructures, etc.).
