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 … See more Several variations of thermal spraying are distinguished: • Plasma spraying • Detonation spraying • Wire arc spraying See more In plasma spraying process, the material to be deposited (feedstock) — typically as a powder, sometimes as a liquid, suspension or wire — is introduced into the plasma jet, emanating from a plasma torch. In the jet, where the temperature is on the order of 10,000 K, the … See more During the 1980s, a class of thermal spray processes called high velocity oxy-fuel spraying was developed.
