1. A coated article comprising:
- (a) a substrate chosen from the group consisting of soft metals, semiconductors and organic polymers; and
(b) an adherent, abrasion resistant coating thereon substantially amorphous and consisting essentially of carbon at the substrate-coating interface, graded in composition remote from the substrate-coating interface, and consisting essentially of one or more of C, or silicon dioxide, and mixtures thereof, where the compositionally graded material remote from the substrate-coating interface comprises SiOx where x is from 1.60 to 2.00.

Abstract
Disclosed is a coated article having a substrate with an adherent, abrasion resistant carbon coating. In a preferred examplification the coating is substantially transparent to visible light and partially absorbing to ultraviolet light. The coating has a relatively disordered portion at the substrate-coating interface and a relatively ordered portion remote from the substrate-coating interface. The coating is a microwave deposited coating with deposition initially at a low microwave energy, and thereafter at a high microwave energy.
