DURABLE, HEAT-RESISTANT MULTI-LAYER COATINGS AND COATED ARTICLES
An article having a surface treated to provide a protective coating structure in accordance with the following method: vapor depositing a first layer on a substrate, wherein said first layer is a metal oxide adhesion layer selected from the group consisting of an oxide of a Group IIIA metal element, a Group IVB metal element, a Group VB metal element, and combinations thereof; vapor depositing a second layer upon said first layer, wherein said second layer includes a silicon-containing layer selected from the group consisting of silicon oxide, silicon nitride, and silicon oxynitride; and vapor depositing a third layer upon said second layer, wherein said third layer is a functional organic-comprising layer, wherein said functional organic-comprising layer is a SAM.

Vapor deposition of metal oxides, silicates and phosphates, and silicon dioxide
Metal silicates or phosphates are deposited on a heated substrate by the reaction of vapors of alkoxysilanols or alkylphosphates along with reactive metal amides, alkyls or alkoxides. For example, vapors of tris(tert-butoxy)silanol react with vapors of tetrakis(ethylmethylamido) hafnium to deposit hafnium silicate on surfaces heated to 300 C. The product film has a very uniform stoichiometry throughout the reactor. Similarly, vapors of diisopropylphosphate react with vapors of lithium bis(ethyldimethylsilyl)amide to deposit lithium phosphate films on substrates heated to 250 C. Supplying the vapors in alternating pulses produces these same compositions with a very uniform distribution of thickness and excellent step coverage.
