Abstract:

A comparative evaluation was made of 18 coatingbase metal systems, six different coatings applied to 3 Nb base materials D-31 alloy, F-48 alloy and unalloyed Nb. The 18 coating-base metal systems were tested under the same conditions in cyclic oxidation 2300 and 2500 F, thermal shock 2 00 to 250 F, bend-oxidation 2500 F nd stress-oxidation 2500 F plus tensile tests. The tests produced directly comparable data between the coating-base metal systems relating to the protective nature of each coating and the effect of the coating and the coating treatment on the mechanical properties of the substrate.
