The molten metal is then atomized with compressed air to create a spray stream that applies the coating onto the surface being sprayed.
Anti-corrosion or engineering coatings can be applied by arc spray and changing between the two is quite simple.
Arc spray systems are commonly considered to be easy to operate and also to automate.
Metallisation has a full range of arc spray systems for hand-held and fully automatic / robotic applications.
Flame spray is a process that uses an oxy-fuel flame to melt wires and in some cases powders or ceramic rods.
The molten material is then atomized with compressed air to create a spray stream that applies the coating onto the surface being sprayed. Anti-corrosion coatings are typically applied with oxy-propane systems.
Engineering coatings are typically applied with oxy-acetylene systems. Where propane is not available, oxy-acetylene systems can apply anti-corrosion coatings.
Flame spray systems are commonly manually operated but it is possible to semi-automate or fully-automate the process if required.
Metallisation has a full range of wire, powder and ceramic rod flame spray systems in hand-held or automated versions.
Plasma is the term used to describe gas which has been raised to such a high temperature that it ionizes and becomes electrically conductive.
In the case of Plasma spraying, the plasma is created by striking an electric arc between the nozzle and the electrode inside the plasma gun. The plasma jet then emerges from the nozzle.
Powder particles are injected into this jet where they soften and then strike the surface at high velocity to produce a strongly adherent coating.
Metallisation offers a Pistol Control Console plasma spray system that is capable to spray a range of commonly available plasma pistols, as well as our own PS50 pistol.
High Velocity Oxygen Fuel (HVOF) is a process to apply very dense, strongly adhered coatings.
A fuel (commonly kerosene or hydrogen) is mixed with oxygen and ignited in combustion chamber.
The combustion gases are accelerated through a nozzle. Powder is introduced into the gas stream where it softens and gathers speed before coating onto the sprayed surface.
These coatings are commonly used as a hard chrome replacement process and produce very dense, hard-wearing coatings.
Metallisation offers two variants of HVOF Pistol Control Consoles to operate either liquid fuel or gas fuel pistols. We also offer our own liquid fuel gas pistol.
Laser cladding falls into the group of processes commonly known as hard-facing.
The laser cladding process is a method of applying a fully dense, metallurgically bonded and virtually pure coating which can be used to increase the wear resistance, corrosion resistance or impact performance of metallic components.
In some cases, all three of the properties can be improved. The process utilizes a precisely focused high power laser beam to create a weld pool into which a metallic powder is applied.
The powder, which is carried by a stream of inert shielding gas, is blown co-axially through the laser beam. The highly accurate nature of the laser beam allows fully dense cladding with minimal dilution (<5%), yet with a perfect metallurgical bond.
The Metallisation MET-CLAD system offers control and integration of the entire cladding process. The system offers control of the process gases, cooling system, laser, powder feed and automation interface safely via an intuitive, touch-screen interface.
