Abstract
A fluid containment article that exhibits a reduced tendency for thermal decomposition products to deposit and adhere to its surface in contact with a hydrocarbon fluid, such as a hydrocarbon fuel, at elevated temperatures. Deposition and adhesion of thermal decomposition products are avoided by tailoring both the composition and surface finish of the surface contacting the hydrocarbon fluid. Preferred characteristics are achieved by appropriately preparing the surface of the article to have a surface roughness characterized by an R.sub.max of up to about 0.4 micrometer, and then depositing an oxide coating on the surface using a deposition process that yields a coating consisting essentially of a metal oxide and the vapors of an organometallic compound used in the deposition process. The oxide coating is directly deposited on the surface of the article, and therefore does not employ an adhesion-promoting layer of the type conventionally used by the prior art to promote adhesion of a metal oxide layer on a metal substrate.
