Read this response and predict the preceding dialog. Coating materials available for thermal spraying include metals, alloys, ceramics, plastics and composites.

See the 2 person dialog:
 -What is meant by Thermal spraying?;
 -Thermal spraying Thermal spraying techniques are coating processes in which melted (or heated) materials are sprayed onto a surface.;
 -What are some examples of the materials that can be sprayed?;
 -The "feedstock" (coating precursor) is heated by electrical (plasma or arc) or chemical means (combustion flame).;
 -Are there any other interesting aspects about this article?;
 -Thermal spraying can provide thick coatings (approx.;
 -How thick can the coatings be?;
 -thickness range is 20 microns to several mm, depending on the process and feedstock), over a large area at high deposition rate as compared to other coating processes such as electroplating, physical and chemical vapor deposition.;
 -What are the most common coatings?;
 -
