Abrasion-resistant plastic articles and method for making them
First Claim
1. A method for preparing an abrasion-resistant plastic article, comprising plasma-enhanced chemical vapor deposition of an abrasion-resistant gradational layer onto a plastic substrate, wherein the composition of the gradational layer changes gradually in a direction perpendicular to the substrate surface from a composition consisting essentially of an interfacial material selected from the group consisting of organosilicon, organometallic, acrylic, and polyolefin materials, to a composition consisting essentially of an abrasion-resistant material selected from the group consisting of silicon dioxide, silicon nitride, silicon oxynitride, silicon carbide, silicon carbonitride, boron oxide, boron nitride, aluminum oxide, aluminum nitride, titanium dioxide, tantalum oxide, iron oxide, germanium oxide, germanium carbide, and mixtures thereof.
