Recent developments in arc spraying

New trends in arc-spraying processes and materials are reviewed. The wide field of applications for arc-sprayed coatings is demonstrated and discussed. Coating systems against corrosion, against wear, and for special applications (e.g. coatings for casting molds or biocompatible layers on artificial implants) are described. New process variants, e.g. spraying with a controlled-wire feed system, use of a pulse power source, or vacuum-arc spraying with one or two wires, are expected to appear with further commercial applications of these techniques.<
