What is Arc spray?

Arc spray uses metal wires as the coating material. An electric arc provides the heat source, one positive and one negative wire.  The opposite charged wires short circuit, forming a plasma temperature of 4,000°C.   The wire melts, and once molten, compressed air to atomize and accelerate the feed metal towards the substrate.

Arc spray can also spray two different wires simultaneously to produce a pseudo alloy, often a bronze and a steel wire are used for coating cylinder heads and engine block.  Cored wires containing tungsten carbides and special alloys can be sprayed as well.

Arc spray systems for aluminium and zinc have extremely high spray rates, and can coat large areas quickly.
