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.
