Abstract
A method for producing a composite element by causing a stream of gaseous rhenium hexafluoride to flow onto a carbon substrate in a chemical vapor deposition reaction. A flow of hydrogen gas causes a reduction of the rhenium hexafluoride to rhenium metal to thereby deposit a uniform layer of rhenium metal onto the surface of the carbon substrate. A fine grain rhenium coating on carbon is produced having an average particle diameter of from about 0.1 to about 25 micrometers. The elements may be used alone or several of them may be bonded together into various articles. Such elements and articles are useful as light weight, high temperature strength, corrosive gas resistant structural elements.
