METALLISATION FLAMESPRAY

In the METALLISATION FLAMESPRAY process, the raw material in the form of a single wire, cord or powder, is melted in an oxygen-fuel gas flame. This molten material is atomised by a cone of compressed air and propelled towards the workpiece.

The molten spray solidifies on the component surface to form a dense, strongly adherent coating suitable for Corrosion Protection or component Reclamation. Sprayed coatings may also be used to provide Wear Resistance, Electrical & Thermal Conductivity or Insulation or Free Standing Shapes.

Major advantages of the Flamespray process are that the coatings are available for almost instant use with no drying or curing times and there is no risk of damaging the component.

METALLISATION ARCSPRAY

In the METALLISATION ARCSPRAY process, the raw material in the form of a pair of metallic wires, is melted by an electric arc. This molten material is atomised by a cone of compressed air and propelled towards the workpiece. The molten spray solidifies on the component surface to form a dense, strongly adherent coating suitable for Corrosion Protection or component Reclamation. Sprayed coatings may also be used to provide Wear Resistance, Electrical & Thermal Conductivity or Free Standing Shapes.

Major advantages of the Arcspray process are that the coatings are available for almost instant use with no drying or curing times and there is no risk of damaging the component. In addition, the deposits possess a higher degree of bond strength than most other thermally sprayed deposits and the use of compressed air and electricity alone mean more economic coatings.

PLASMA SPRAY

Plasma is the term used to describe gas which has been raised to such a high temperature that it ionises and becomes electrically conductive. In the case of Plasma spraying, the plasma is created by an electric arc burning within the nozzle of a plasma gun and the arc gas is formed into a plasma jet as it emerges from the nozzle.

Powder particles are injected into this jet where they melt and then strike the surface at high velocity to produce a strongly adherent coating. Almost any material can be sprayed including metals, ceramics and plastics. The workpiece remains cool because the plasma is localised at the gun.

HYPERSONIC SPRAY PROCESS

Liquid fuel and oxygen are fed via a premixing system and at high pressure into a combustion chamber where they burn to produce a hot high pressure gas stream. This is expanded through a laval type nozzle increasing the gas velocity to around 1500m/sec and the pressure to slightly above atmospheric. At this stage the powder can easily be injected into the gas stream.

This gas stream heats and accelerates the powder particles within the confines of the secondary nozzles so that they impact with tremendous energy upon the substrate material. The MET-JET II System does not melt powders but only softens them. Because less heat is imparted to the particles and dwell times are very short oxidation and decomposition are minimal in MET-JET II coatings.
