Metal Spraying Systems: Flame Spray, Arc Spray, Plasma Spray and High Velocity Oxygen Fuel (HVOF) Spray Systems
There are four commonly used processes in metal spraying, Flame spray, Arc spray, Plasma Spray and High Velocity Oxygen Fuel (HVOF) spray systems. The metal spraying process universally melts or softens the materials to be sprayed.
All four processes use a different combination of heat, material delivery and projection method:
- Flame spray uses gas and oxygen to melt the wires before spraying.
- Arc spray uses DC electrical power to melt the wires before spraying.
- Plasma Spray uses electric arc in an inert gas to melt the spray powders, ceramics, metals or cermets.
- High Velocity Oxygen Fuel (HVOF) uses an accelerated oxygen fuel flame to soften the spray powders and project onto the substrate with high levels of kinetic energy.
Galvanising and Corrosion Protection Spraying
Metallisation Flame spray and Arc spray equipment is used to apply galvanising / corrosion protection coatings of zinc, aluminium and zinc/aluminium alloys onto steelwork such as bridges, gantries, ships, pylons and vehicles.
All four processes can also be used for engineering coatings to rebuild parts such as tank wheels, bearing surfaces, shafts and clutch parts. Engineering coatings are used to provide wear resistance, thermal barriers, electrical and thermal conductivity, chrome replacement and insulation across many industries.
Metal spraying is ideal for rebuilding undersized shafts, which have been worn down through normal wear and tear. The worn surface is sprayed with steel, or a range of other materials, to rebuild the shaft to its original size
Metal spraying can also enhance the properties of the substrate for example it can enable a designer to combine the benefits and strength of lightweight aluminium, with the surface characteristics and durability of steel.
A specific example would be if aluminium tank wheels were left uncoated they would quickly wear down working against the steel drive mechanism. Metal spraying the tank wheels with steel will help prolong their life.
Major advantages of the metal spray process are that the coatings are available for almost instant use, with no drying or curing times, and there is no risk of thermal distortion of the component.
The process can be applied in-house or on-site and there is virtually no limit to the size of structure that can be coated, unlike for instance plating, galvanising or PVD coating.
Since it is a metallurgically cold process there is no damage to the substrate and almost any material can be coated with almost any other. For instance aluminium can be coated with tungsten carbide or steels. Soft carbon steels can be coated with harder wearing steels or ceramic coatings etc.
This immense versatility allows thermally sprayed coatings to be used where others would be impossible or excessively expensive.
