Abstract:
A method of depositing a plurality of layers on a substrate, the method comprising steps of:flowing a plasma gas in a plasma generation chamber in communication with a deposition chamber, the deposition chamber having a lower pressure than the plasma generation chamber, the article being disposed in the deposition chamber; generating an arc in the plasma generation chamber to create a plasma, which flows into the deposition chamber; injecting a first material comprising and a first oxidant at least one of a polymerizable hydrocarbon and an organosilicon material into the plasma and reacting the first material to form an interlayer on the substrate, the interlayer comprising a polymerized organosilicon material; and injecting a second material comprising and a second oxidant at least one of an elemental metal and an organometallic compound into the plasma and reacting the second material to form a second layer comprising an inorganic ultraviolet absorbing material on the interlayer, the second material comprising a gaseous reagent, wherein the interlayer has a coefficient of thermal expansion that is between that of the substrate and the second layer.
