Method for producing diamond-like coatings and coated articles made thereby.

摘要

The method involves providing a substrate to be coated, providing a cathode of vitreous carbon or a pyrolytic graphite cathode and initiating a cathodic arc discharge with the arc spot on the cathode surface. The resulting carbon plasma is directed toward the substrate to form a coating on the substrate, the coating being macroparticle free. The cathodic arc discharge is powered by a capacitor to produce a pulsed arc discharge. The arc voltage is between about 20 to 60 volts, and the arc current is at least about 50 amps. The discharge is carried out in a magnetic field.
