Thermal Spay Coating

Thermal spraying coating is the processes in which melted (or heated) materials are sprayed onto a surface. 
Thermal spraying can provide thick coatings (thickness range is 20μm 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 & chemical vapor. They are fed in powder or wire form, heated to a molten or semimolten state and accelerated towards substrates in the form of micrometer-size particles. 
Coating quality is usually assessed by measuring its porosity, oxide content, macro and micro-hardness, bond strength and surface roughness. Generally, the coating quality increases with increasing particle velocities.

The following coating process are all thermal spray coating.
Plasma spraying
Detonation spraying
Wire arc spraying
Flame spraying
High velocity oxy-fuel coating spraying (HVOF)
Warm spraying
Cold spraying

Coating materials are available for thermal spraying include metals, alloys, ceramics, plastics and composites.
