Thermal spraying techniques are coating processes in which melted (or heated) materials are sprayed onto a surface. The "feedstock" (coating precursor) is heated by electrical (plasma or arc) or chemical means (combustion flame). Thermal spraying can provide thick coatings (approx. thickness range is 20 microns to several mm, depending on the process and feedstock), over a la. VariationsSeveral variations of thermal spraying are distinguished: • Plasma spraying• • Wire arc spraying. .
A typical thermal spray system consists of the following: • Spray torch (or spray gun) – the core device performing the melting and acceleration of the particles to be deposited• Feeder. .
The detonation gun consists of a long water-cooled barrel with inlet valves for gases and powder. Oxygen and fuel (acetylene most common) are fed into the barrel along with a charge of powder. A spark is us. [pdf]
