Wear, defined as deterioration due to use, of water wheel at a hydroelectric power station is caused primarily by three factors, namely corrosion, abrasion and cavitation. It is the purpose of this paper to study on abrasion resistance of various materials against sand in a rapid current of water and their hardface-welding method, and to analize some of the aspects of abrasion mechanism. Abrasion testing apparatus, method and results are described together. As an abrasion phenomenon is very complicated, homogeneous C-steel pieces were chosen for analizing abrasion mechanism. Harder material is not always more abrasion resistant and high C-steeil as quenched is not more abrasion resistant than that tempered at 400℃…500℃.
