 In
the Arc Spray process, the raw material in the form of
a pair of metallic wires is melted by means of an electric
arc. The molten material is atomised by 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 and Thermal
Conductivity or Free Standing Shapes.
Major advantages of the Arc Spray 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 then
most other thermally sprayed deposits and the use of compressed
air and electricity alone mean more economic coatings.
