Abstract:
The reuse capabilities of coated niobium were investigated. The investigation included 1 the establishment of baseline coating performance and mechanical properties 2 the effects of design on the performance of coating niobium 3 the effects of local coating damage and 4 the effects of multiple reentry flights on the coating emittance. The coating used was Sylvanias R-512E and the niobium alloy used was Cb-752. Basic oxidation tests were conducted with results from each substantiating good coating reproducibility. The coated columbium heat shield specimens proved to have an extensive reuse capability of greater than 100 flights.
