Title:
The Evaluation of High Temperature Materials. Part 1: Evaluation of Coatings for Refractory Alloys. Part 2: Materials Evaluation With an Arc-Plasma-Jet
Report Date:
1964-03-01
Abstract:
This report describes the evaluation of candidate materials systems for high temperature service and is presented in two separate parts: the first pertains to the development of laboratory tests for the evaluation of refractory alloy coatings; the second, to the arc-plasma-jet evaluation of ablative materials, impregnated porous ceramics, refractory composites, and sprayed ceramic coatings. Part I describes analytical and experimental approaches leading to the development of an orderly series of tests designed to characterize the oxidation behavior of refractory alloy coatings and to determine their influence upon the physical and mechanical properties of the base metal. Part II describes the screening of 78 different high temperature materials with an arc-plasma-jet testing facility. The systems evaluated fell into four general categories: ablative materials, impregnated porous ceramics, refractory composites, or sprayed ceramic coatings. Testing procedures were adjusted for each class of materials to emphasize particular performance characteristics.
