DESIGN DATA STUDY FOR COATED COLUMBIUM ALLOYS

Abstract

Design data properties were determined for two protective coating- columbium alloy systems involving Pfaudler and TRW oxidation protective coatings on Fansteel-85 columbium alloy up to temperatures of 2600 F. Prior to the design data study, preliminary screening oxidation, bend and prestrain tests were conducted on seven oxidation protective coatings applied to D-14 and FS-85 columbium alloys. Based on the screening test results, Pfaudler and TRW coatings were selected for the mechanical properties evaluation. The following design properties were determined for uncoated and Praudler and TRW coated 30 mil FS-85 alloy sheet: (a) coating cyclic oxidation protective life, (b) tensile properties of uncoated (in vacuum) and coated (in air) sheet, (c) coating deformation tolerance and (d) stress rupture properties of coated sheet (in air).
