Abstract:
A method of depositing a plurality of layers on an article, 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 into the plasma and reacting the first material to form an interlayer on the article, the interlayer comprising a polymerized organosilicon material; and injecting a second material 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.
