N2 - A preliminary investigtion was conducted on the metallurgical treatments produced on a planar workpiece connected as an anode in a pulsed 1 kA vacuum arc. Generally a combination of deposition and heating effects could be produced. Very high deposition rates (approximately 25 microns/s) are calculated based on the ion flow, and even higher rates (exceeding 100 microns/s) are observed if part of the macroparticle flow is incorporated into the coating. The concurrent workpiece heating can, depending on arcing conditions, encourage interdiffusion of the coating and substrate materials forming a metallurgical bond, melt the substrate surface in the presence of the plasma flow forming surface alloys, and induce martensite formation near the surface of steel workpieces.
