ABSTRACT:
Articles for hot hydrocarbon fluid wherein the surface for contacting the fluid is a metal oxide, amorphous glass or metal fluoride diffusion barrier material coated on a metal substrate. The metal oxide, amorphous glass or metal fluoride is deposited by chemical vapor deposition (CVD), e.g., by effusive CVD of an organometallic compound on the surface without the use of carrier gas, without pre-oxidation of the surface and without thermal decomposition of the diffusion barrier coating material. Examples of coating materials deposited by effusive CVD are SiO.sub.2, TiO.sub.2, spinel and Al.sub.2 O.sub.3. The articles having the coated surfaces find utility in components subjected to high temperatures wherein the components are in contact with hydrocarbon fluids without additives, without special attention to quality control and without the need for special processing.
