INFLUENCE OF BOOST GLIDE RE-ENTRY VEHICLE ENVIRONMENT ON COATED AND BARE REFRACTORY METALS.

Abstract

Uncoated and defect-containing coated refractory metal specimens were subjected to laboratory simulations of a boost glide re-entry vehicle flight environment. Measurements and visual examination determined the effects of the re-entry flight environment. Weight change, dimensional change, and extent of substrate contamination were measured for each specimen. An x-ray diffraction analysis was performed on the surface of representative specimens. Knoop hardness traverses were made through a section of the tested specimens. Each surface was photographed and typical areas and defects were microphotographed for evaluation. (Author)
