In the previous report, results of abrasion testing of homogeneous Carbon steel pieces were reported. It is the purpose of this research to study on abrasion resistance of various hardface-welded depositmetals against sand in a rapid Current of water and to analize some of the aspects of abrasion mechanism. Very hard depositmetals, as welded, were chosen for analizing abrasion mechanism. When shooting angle is 30°, the harder the material is, the more abrasionresistant, but when 90°, material of which hardness is Vickers 400∿500,is most abrasion resistant. Then, observations of sand scratches on mild steel- and quenched steel-pieces were made by means of microscope and profilometer.
