The arc spraying (AS ) is a view of the high deposition rates an inexpensive coating process. An arc is struck between the wire-shaped spray material, which leads to the melting of these. Subsequently, the molten particles are atomized by a gas, accelerated and applied to the component surface.
By using different wire materials are matched to the specific use pseudo alloys can be produced. Also can be generated using ceramic or hard material fillings, hard coatings by the use of cored wires.
