Abstract

The present invention is a non-metallic article that has been coated with a diamond-like carbon (DLC) coating. A coated article of the present invention has increased hardness, increased abrasion resistance, and a reduced coefficient of friction when compared with the same properties of the article prior to the article being coated. DLC coatings of the present invention are applied in a chamber filled with hydrocarbon plasma and with application of electrical pulses.
