More About Thermal Spraying
Thermal spraying is a group of processes in which
finely divided in ceramic, metals & carbide,
surfacing materials are deposited in molten condition on
a prepared substrate to form a spray deposit. The
surfacing material may be in the form of powder, rod or
wire. The thermal spraying gun generates the necessary
heat by using combustible gases or an electric arc. As
materials are heated, they change to a molten state, and
are accelerate by a compressed gas. The confined stream
of particles are conveyed to the substrate. The
particles strikes the surface, flatten and form thin
platelets that conform and adhere to the irregularities
of the prepared surface and to each other. As the
sprayed particles impinge upon the substrate, they cool
and build up, particle by particle, intro a structure,
thus coating is formed.
PROCESSES
1. FLAME SPRAY PROCESS
Flame, where in it gets melted, the melt is then
propelled on to a prepared surface by the gas pressure
itself or by additional air pressure.
2.WIRE FLAME SPRAY PROCESS
This process can be used to spray any metal which can
be drawn in the form of wire and which melts at 3500� C.
Here again, coating material (wire form) is melted in an
oxy - acetylene flame. The melt is then atomized by a
strong blast of compressed air and then propelled on to
prepared surface.
3. PLASMA SPRAY PROCESS
PLASMA is often considered the fourth state of matter,
after solid, liquid and gas. In this process, plasma is
used as a heat source which has a flame temperature of
about 16000� C. A high energy arc struck between an
anode and a cathode in a specially designed spray gun
excites the plasma forming gas. The excited gas is then
forced through a convergent - divergent Nozzle so that
it gains velocity. As the excited gas exits the Nozzle,
it returns to its normal state releasing extreme heat.
Coating material in the powder form is then introduced
in this flame, where in it gets melted and gets
propelled on to the prepared surface to form
coating.
Note : Plasma Application Processors has two Plasma
systems 40 KW & 80 KW (High Energy Plasma) to
cater wide range of industrial application.

4. High Velocity Oxy-Fuel Process ( HVOF)
The HVOF process uses an oxygen-hydrogen mixture to
produce quality coating. Fuel gases are mixed in a
proprietary siphon Plug system in the front portion of
the gun. Thoroughly mixed gases are ejected from a
nozzle and ignited external to the gun. Ignited gases
form a circular flame configuration which surrounds the
powdered spray material as it flows through the gun and
into the flame. Combustion temperature is approximately
2700� C (5000�F) and flame velocity in the range of 7000
ft / sec. The high velocity particles flatten when
impacting the substrate to form a dense tightly bonded
coating.
