Experiments are described and results discussed concerning the erosion/corrosion effects that coal slurries have on various materials. These experiments, performed in a laboratory-scale wear test apparatus, use slurries containing silica sand, Kentucky #9 coal. Pond Creek coal, and refuse from a coal preparation plant. It was found that the guantity of ash is not as important in overall materials wear as is the composition and location of ash within the coal matrix. The wear of the steel materials under slurry impingement exhibit linear behavior for silica sand and Kentucky #9 coal. However, the wear of the same materials under Pond creek coal slurry and coal refuse slurry was not linear with increasing time of exposure. Factors that contribute to this behavior are discussed with respect to the characteristics of the slurries and materials.
