Three alloys were tested in the test facility which has been designed to simulate the aerodynamic and thermodynamic conditions in the turbine. The effects on erosion due to the high tempeature coal ash gas stream was determined at several gas temperatures, particle velocities and angles of attack. The test results for 304 stainless steel, Rene 41 and A286, and the corresponding conclusions are presented. In addition, a series of experiments were conducted to determine the effects of fly ash constituents on the erosion of iron and nickel base alloys. A new semi-empirical equation has been obtained for the prediction of metal erosion due to the fly ash.
