1. A liquid anodic arc deposition system for depositing a material on a substrate comprising:
- a vacuum chamber;
an anode assembly comprising;
an anode of spooled wire of said material to be deposited, said spooled wire having a free end and a spooled end; and
a cathode assembly comprising;
a cathode; and
an initiator electrode juxtaposed with and separated fromsaid cathode by an insulator,said anode assembly and said cathode assembly located within said vacuum chamber in close juxtaposition,said anode, in use, forming a liquid region from which the deposition material is vaporized.

Abstract
An anodic vacuum arc deposition system for rapidly depositing a high quality, small grain size, coating on a workpiece. The anodic vacuum arc deposition system includes an arc initiator and an anodic electrode having a continuous feed. The anodic vacuum arc deposition system may be configured with a coaxial anode and cathode. A plurality of coaxial electrodes may be used to deposition coat a large area and/or to sequentially deposit a series of layers each of a different material.
