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:
- For arc and flame spraying systems
- Bond coats
- High temperature corrosion protection
