The story took place in 1922. Among other things, the first person received insulin injection as a cure for diabetes θηκε the BBC… was founded… and they started building the Yankee Stadium. It was also the year that Metallisation opened its doors for the first time, offering a new solution to corrosion problems in steel structures.
Like the others, we have come a long way since then. To date, we are the UK's sole developer, manufacturer and global supplier of a complete range of metal spraying equipment and consumables. Equipment such as Arcspray, Flamespray, Plasma, HVOF and Automated Spraying Systems.
From our strong history in the supply of corrosion protection equipment, our customer base is increasingly using our products for mechanical coatings. Whether it's steel coatings applied by arc equipment or flame spraying to ceramics and carbide coatings used by plasma or HVOF equipment, our easy-to-use, durable and reliable systems are becoming a natural choice for many users around the world.
Since 1922, Metallisation has been the leading developer and manufacturer of thermal spray equipment and consumables for Arcspray, Flamespray, Plasma, HVOF, Laser Cladding and Automated Spraying Systems.

COMPARISON OF METAL SPRAYING WITH GALVANISING
Galvanising is a well established process for applying a corrosion protection layer of zinc to steel.
Treated steelwork is immersed briefly in molten zinc and the coating builds up very quickly.
Galvanised layers are usually of even thickness, dense and metallurgically bonded to the steel.
Thickness is typically 0.002 - 0.006 in (50 - 150μ). Coating compositions are sometimes varied to
control deposit thickness and give better protection in certain specific environments.
Metal Spraying Offers the Following Advantages Over
Galvanising
• Low heat input during spraying eliminates the risk of thermal distortion
• Low heat input eliminates the risk of thermal metallurgical degradation
• Sealed hollow fabrications may be treated without risk of explosion
• The process is not limited to zinc. The coating material may be selected specifically for the
environment
• Coating thickness may be varied from place to place to provide extra protection in critical areas
• There is no limit to the size of article which can be treated
• Articles can be treated on site
• There is no effluent disposal problem
• Reduced stocks of zinc are required. Working capital is not tied up in a molten zinc bath
• Fuel is not needed to keep zinc molten when the process is not working
• Metal spraying is used to restore corrosion protection on damaged areas of welded galvanised
steel.
PROTECTION AGAINST CORROSION
The benefits of sprayed metallic layers
01. There is almost no limitation on the size of component or structure which can be treated.
02. The materials are simple to apply using Metallisation combustion flame or electric arc spraying equipment. Operators can be trained in a relatively short time and with a small amount of practice are capable of producing consistently sound and even coatings on properly grit blasted surfaces.
03. Where large areas or large numbers of components are to be sprayed, the Metallisation wire fed spraying equipment is easily mechanised or fully automated. Both the combustion gas and electric arc spraying systems have efficient stop/start devices for production economy.
04. The process itself is simple involving only two or three stages; spraying is preceded by grit blasting and may be followed by sealing of the deposit. This simplicity makes quality control relatively easy and offers fewer stages for errors to occur.
05. Sprayed metal coatings may be handled immediately after treatment. There are no protracted drying times and factory floor space can be more efficiently utilised.
06. Properly applied sprayed metal coatings are more robust than paint systems and are consequently able to withstand rougher usage.
07. Sprayed zinc, aluminium and associated alloy coatings give long lives in most naturally occurring environments. (See Application Data Sheet AC-AC-002 for more detail). Ten years to first maintenance is common and over twenty years may be readily achieved with the appropriate system.
08. There is no distinct limit to the thickness of sprayed coatings. Zinc may be sprayed to over 3mm and unlike galvanising, thickness may be varied from place to place to provide protection in critical areas.
09. Metallisation zinc, aluminium and associated alloy spraying wires are of consistent quality and purity. Properly stored, shelf life is indefinite; there are no settlement problems as may be experienced with powder spraying materials and no mixing as required with paints.
10. Even if a sprayed deposit is locally damaged, the sacrificial action particularly of zinc prevents corrosion from edges and discontinuities. It may also delay the onset of rusting of structures which have been neglected.
11. Although bare metal sprayed coatings give long lives they may be sealed to extend the life time or enhance the visual appearance.
12. The surface being sprayed remains cool. Consequently there is no risk of heat distortion or metallurgical degradation of load bearing steel structures. Sealed tubular or hollow sections can be coated externally without danger.
13. The sprayed metal surface maintains the efficiency of friction grip areas and ensures their effectiveness throughout the life of the structure
14. Thick anti-corrosive paint systems are generally unnecessary but the texture of "bare" sprayed coatings provides an excellent "key" for subsequent paint treatment. In most cases where the sprayed metal is properly sealed, these need only be applied for decorative purposes.
15. The nature of the equipment makes it ideal for either factory or site application and coatings can be deposited in ambient conditions totally unsuited to other methods of protective treatment.
