Metallising

A1 Metallising Services Pty Ltd boasts 12 dedicated metallising booths specially equipped to facilitate the following metallising processes; Three HVOF (High Velocity Oxygen Fuel Systems); Nine Electric Arc Spray Systems; One Rokide Ceramic System; Ten 12E Gas Systems; One 6P and Three 5P Gas Spray systems.

With this selection of metallising processes we are able to offer our customers a large range of repair options to suit the varied operating environments their components are subjected to.

From the basic dimensional restoration of worn components, to the protection against wear, erosion, and most corrosive environments, A1 Metallising Services Pty Ltd can offer a metallising solution to meet our customers’ needs.

Gas Metallising
Gas metallising is a process, in which surfacing materials, either wire or powder are heated to their plastic or molten state by an oxy-acetylene flame in the nozzle system of the spray gun, and propelled onto a prepared surface.

Twin-Arc Electric Metallising
The arc spray process uses electrical power for heat generation. Spray materials are solid or cored wire forms. Two continuously fed wires are melted by an arc operating between each wire, and the molten metal is atomized and propelled to the substrate by a high velocity gas jet, usually air.

Ceramic Spraying
Ceramic Oxide materials such as “Chrome Oxide”, “Aluminium Oxide”, “Alumina Titania”, are deposited onto a prepared substrate by means of a high-temperature gas stream produced by the “Gas Metallising” process.

Rokide Ceramic Coatings
This system is unique because it utilises ceramic oxide rods. The rods are melted in a patented spray unit, which projects only fully molten particles onto a prepared substrate. These particles have high kinetic energy and high thermal mass, so they remain molten until they reach the substrate.

High Velocity Oxygen-Fuel Coatings
The high velocity flame spraying system, produce coatings which are of high density and 99% porosity free, with excellent cohesion between deposited particles and adhesion to the substrate. A great variety of materials can be HVOF sprayed, with materials containing carbides being of exceptional quality as very few carbides undergo conversion into a composite carbide through this process.

Hard Facing
With this method, a self-fluxing material is sprayed onto a prepared substrate by means of the gas metallising process. Heating it to its plastic or molten state using an oxy-acetylene gas flame then fuses the sprayed deposit. The fusing temperature ranges from 1020ºC to 1140ºC.
