Robotic weld overlay coatings for erosion control. Quarterly technical progress report, January 1995--March 1995

摘要

Research is presently being conducted to develop a criteria for selecting weld overlay coatings for erosion mitigation in Circulated Fluidized Beds. During the last two quarters tensile tests were performed at 400(degrees)C for the Ultimet, Inconel-625, 316L SS, C-22, and Stellite-6 wrought alloys. Also, the erosion tests for these materials at 400(degrees)C were completed. The results of mechanical and erosion tests are used to correlate mechanical properties of selected wrought alloys such as tensile toughness, ductility, strain hardening coefficient and yield strength to their erosion resistance at 400(degrees)C. Preliminary results of correlations between erosion resistance of wrought alloys at 400(degrees)C and their mechanical properties are presented in this progress report.
