The subject program is designed to gain an improved understanding of the various mechanisms of dust erosion, as a basis for possible future development of turbine materials with improved innate erosion resistance. A materials science approach to the problem is emphasized, to observe, measure, and study erosion phenomena at the target surface. The object is to define working physical and mathematical models of the erosion processes, from consideration of both erosion data and phenomenological information gathered. The experimental program is organized to evaluate the relative importance of erosion influencing variables introduced by the carrier gas, the dust suspension and the target materials themselves. Two functional tasks are reported 1 the execution of the erosion test program, including the design and construction of special test equipment 2 the analysis of erosion data and development of physical and mathematical models to define erosion mechanisms.
