The Long Term Materials Test has completed 250 hours of Corrosion Validation Testing. Metallographic analysis of the materials specimens is underway, but preliminary examination indicates that the corrosion is severe relative to that experienced at Exxon and CURL. The possible causes are being assessed before continuing the test. Two operating problems were encountered during the validation testing. Hard deposits formed on the cascade pressure surface and plugged the passage when the combustor was operated at 1800/sup 0/F. Dropping combustor temperature to 1750/sup 0/F alleviated the problem. The in-bed heat exchanger also experienced severe erosion. The erosion problem has been solved and the test completed.
