Title:
COATED ARTICLE AND METHOD FOR PREVENTING FUEL THERMAL DEGRADATION DEPOSIT
Document Type and Number:
Japanese Patent JP2928063
Kind Code:
B
Abstract:
PURPOSE: To prevent or reduce the deposit of thermal degradation products of a hydrocarbon fluid on the surface to be brought to contact with the fluid.
CONSTITUTION: Articles for hot hydrocarbon fluid wherein the surface to be brought to contact with the fluid is a metal oxide, amorphous glass or metal fluoride diffusion barrier material coated on a metal substrate are provided. The metal oxide, amorphous glass or metal fluoride is deposited by chemical vapor deposition(CVD), e.g. by effusive CVD of an organometallic compd. 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 Ta2O5, SiO2, TiO2, spinel and Al2O3.
