The erosion-corrosion wear resistance of C1020 mild steel, C1062 carbon steel at 4 hardness values, Ni-hard cast iron, 4 stainless steels and titanium was assessed in coal-water slurries. Corrosion resistance was found to be more important than hardness for wear resistance of these metals in coal slurries. The best overall performance of the metals tested was obtained from oxidised Ti. Cathodic protection was effective in greatly reducing the wear rate of C1020 steel in coal slurries. De-aeration reduced wear rates of C1020, C1062, Ni-hard and 440C SS. Data are presented on the effect of velocity, particle size, coal concentration, and dissolved oxygen concentration on erosion-corrosion of these metals in coal slurries.
