Disclosed are improved abrasion-resistant plasma coatings adapted to be coated onto substrates including polymeric substrates, glass, and metal. The method of plasma coating the substrates comprises restricting the monomer to be a silane, disiloxane, silazane, or disilazane which is substituted with at least one alkoxy group per silicon atom wherein the alkoxy group is selected from methoxy groups, ethoxy groups, and mixtures thereof. The plasma coating is applied under plasma coating conditions for a time adequate to form an abrasion-resistant coating having sufficient thickness so as to possess a Taber abrasion resistance of less than 10% haze development after 100 cycles. Abrasion resistance of some disclosed coatings is less than about 5% development after 1,000 cycles.
