Abstract
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 abrasion resistant, 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.
