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 micrometers to several mm, depending on the process and feedstock), over a large area at high deposition rate as compared to other coating processes such aselectroplating, physical and chemical vapor deposition. Coating materials available for thermal spraying include metals,alloys, ceramics, plastics and composites. 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.

Combustion or electrical arc discharge is usually used as the source of energy for thermal spraying. Resulting coatings are made by the accumulation of numerous sprayed particles. The surface may not heat up significantly, allowing the coating of flammable substances.

Coating quality is usually assessed by measuring its porosity, oxide content, macro and micro-hardness, bond strength andsurface roughness. Generally, the coating quality increases with increasing particle velocities.

Several variations of thermal spraying are distinguished:

Plasma spraying

Detonation spraying

Wire arc spraying

Flame spraying

High velocity oxy-fuel coating spraying (HVOF)

Warm spraying

Cold spraying

NiAl 80/20 can be used as an adhesive coating and require minimal surface treatment. Bond strengths in excess of 9000 psi can be obtained on blasting surfaces of gravel. It has good resistance to high temperature oxidation and abrasion, and excellent resistance to impact and bending.
Application:

1. For arc and flame spraying systems
2. Bond coats
3. High temperature corrosion protection

SURFACE PREPARATION:
Surface should be clean, white metal, with no oxides (rust), dirt, grease, or oil on the surface to be coated. Note: It is best not to handle surfaces after cleaning. Recommended method of preparationis, to grit blast with 24 mesh aluminum oxide, rough grind, or rough machine in a lathe.
