- Low-voltage, high-current electrical dischargeThe conventional cathodic arc is a low-voltage, high-current electrical discharge between two electrodes in a vacuum or in a gas, where the discharge current is concentrated on random cathode spots...www.sciencedirect.com/topics/engineering/cathodic-arc
Cathodic arc deposition - Wikipedia
Cathodic arc deposition or Arc-PVD is a physical vapor deposition technique in which an electric arc is used to vaporize material from a cathode target. The vaporized material then condenses on a substrate, forming a thin film. The technique can be used to deposit metallic, ceramic, and composite films.
