Definition - What does Arc Spray mean?
Arc spray is a welding process that uses electric arcs to melt wires. The molten metal is propelled with compressed air (via atomization) to create a spray stream that is applied as a surface coating.
Corrosionpedia explains Arc Spray
An arc spray is used for various anti-corrosion and engineering coating applications. It can replace galvanizing and chrome plating coatings. It provides high ductility with low stress, and provides high surface bond strength. Some arc spray application systems are fully automated, while others are manual.
