METALLURGICAL EXAMINATION OF LB-2 COATED TITANIUM BOLT AND SHEET,

Abstract

An LB-2 slurry coating was applied to a 6 A1-4V titanium bolt and to a coupon of AMS4901 titanium sheet. The bolt and sheet were then subjected to a standard diffusion cycle. As a result of the diffusion cycle, the sheet became embrittled. Metallurgical examination showed no detrimental effects that resulted directly from the application of the LB-2 coating. The coating appears to be porous and brittle in some areas on the bolt; the LB-2 coating on the titanium sheet showed numerous cracks. Dissolution of the base metal in either the bolt or sheet was not in evidence. (Author)
