Tantalum Alloy Structural Fasteners

Abstract

A survey of available tantalum coatings was conducted to determine which might be capable of protecting threaded fasteners from oxidation at up to 3500F. Sufficient tests were run on each selected coating to demonstrate that no coating is available to provide consistent protection at 3500F, or in fact for 3000F. Problems associated with thread forms and stress-relaxation were studied, but only in a general way due to the limitations imposed by the lack of satisfactory coatings.
