The erosion/corrosion behavior of five commercial high temperature materials (alloy 800H, AISI 314, alloy AC66, alloy 45-TM, alloy 625) was investigated in synthetic waste incineration atmosphere using silica sand as erosive particles. It was found that the erosion/corrosion behavior depended sensitively on the particle velocity. As long as the velocity was low (880 m/h) corrosion attack occurred mainly by chlorination. Consequently materials with a high resistance to chlorine-containing atmospheres like alloys 45-TM and 625 showed the lowest corrosion rates. If the particle velocity was increased to 1660 m/h, material wastage by erosion dominated.
