Metal Spraying onto Wood
Wood is another material that can be subjected to the Metal Spray process.
An undercoat of zinc is usually applied - about 100 µm thick using either Flame or Arc spraying. This is then followed by a top coat that will produce a desired colour phase, such as Aluminium Bronze or Brass, deposited until approx. 3 mm thick. A grinder, buffing, wire brushes or a chemical treatment, can be used to create fantastic metallic arts, along with being utilised in a plethora of other applications e.g. copper work surfaces, decorative Pieces & Furniture, to name a few.
One of the benefits of such coatings on wood is the corrosion protection it offers. For example, the copper coating on the wood or fibreboard can effectively protect the wood from fungi and mildew. Thermal spray copper coatings have proved to have the potential to protect wood from biological degradation, while also serving as an antimicrobial coating.
