DESIGN DATA STUDY FOR COATED COLUMBIUM ALLOYS
Abstract
The design data study of Pfaudler and TRW protective coated 30 mil Fansteel 85 alloy sheet is in progress. Specimen designs and preparation, coating application techniques and evaluation test procedures are presented. Cyclic oxidation tests in air at 1600 to 2600 F were conducted to establish basic protective characteristics of the two coating-base metal systems. Tensile properties of FS-85 alloy sheet were determined (1) uncoated in vacuum and (2) coated in air from room temperature to 2600 F. A comparison of the mechanical properties of uncoated and coated FS-85 alloy is graphically presented. Tentative results are reported concerning an evaluation of the prestrain tolerance of the two coatings on FS-85 alloy sheet at various temperatures and the resultant effect on oxidation protection at 1600 and 2600 F. Stress rupture properties of coated FS-85 alloy are being determined in air at temperatures from 1600 to 2600 F, and tentative results are presented. (Author)
