Pulsed carbon plasma apparatus

The present invention provides a pulsed carbon plasma apparatus to produce a diamond-like carbon coating over an extended object, the coating having a high degree of thickness uniformity achieved by scanning the plasma flow over the surface of the object. The pulsed carbon plasma apparatus of the in...

Beschreibung
Zusammenfassung:	The present invention provides a pulsed carbon plasma apparatus to produce a diamond-like carbon coating over an extended object, the coating having a high degree of thickness uniformity achieved by scanning the plasma flow over the surface of the object. The pulsed carbon plasma apparatus of the invention comprises a carbon plasma flow scanning device having at least one pair of deflecting coils, where the deflecting coils have, in the scanning plane, a different number of turns on opposite sides. The object may be made of metal, ceramic, glass or plastic. The coatings may be used to improve life and operating performance of tools and machine parts, and as decorative coatings.
