Abstract : The screening evaluation tests on 7 oxidation protective coatings applied on D-14 (Cb-5Zr) alloy sheet were completed. Oxidation protective life for the coating systems was determined in the as coated condition at 1600, 2000, 2300 and 2600 F, and at 2000 and 2600 F after room temperature prestrain in both the elastic and plastic regions. Room temperature bend ductility of coated D-14 alloy sheet was determined in the as coated condition and after 50 hr oxidation exposure in air at 2000 and 10 hr at 2600 F. The comparative coating property data is presented both pictorially and graphically such that a thorough analysis can be made in selecting the coatings for the design data study phase of the program. A brief outline of the revised design data study phase of the program is presented. (Author)
