PRODUCT OVERVIEW
Nickel based alloy wire
Our company use Vaccum furnace and casting control to mak the NiAl
alloy solid wire, it is specially used for arc spray boning layer.
Specification of wire: 1.6mm, 2.0mm, 15kg/spool.Applying technique: Arc spray
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
