Abstract
Apparatus for cathodic vacuum-arc coating deposition. The apparatus includes a mixing chamber, at least one input duct projecting from a first end wall of the mixing chamber, and an output duct projecting from a second end wall of the mixing chamber. Coupled with each input duct is a plasma source adapted to discharge an ion flow of a coating material into the mixing chamber, which is subsequently directed to the output duct. A first solenoidal coil disposed about a side wall of the mixing chamber creates a first magnetic field inside the mixing chamber for steering the ion flow. A second solenoidal coil is disposed adjacent to the first end wall and aligned substantially coaxially with the output duct. The second solenoidal coil creates a second magnetic field inside the mixing chamber for steering the first ion flow. The electrical currents flow through the first and second solenoidal coils in opposite solenoidal directions.
