Wire spraying is used to apply a number of different metals and their alloys.
Main Applications
Commonly used in the build up of mis-machined parts; for applying corrosion resistant coatings to steelwork and as a bearing material.
Flame Spray Wire Process Description
A wire spray gun uses oxygen and acetylene to produce a flame through which metal wire is fed and melted into droplets.
The resultant molten metal is atomised by compressed gas and sprayed on to the prepared surface to form the coating.
In many cases, wire spraying is a lower cost alternative to the plasma spray process for applying metals and is generally capable of building up thicker coatings than plasma. However, the range of available materials that can be sprayed is much lower than that for plasma.
General Flame Spray Wire Coating Characteristics
- typically contains a higher level of oxide and porosity
- generally possesses a greater surface roughness finish in comparison to other thermal spray processes
