Wear Resistance Property of Stainless Steel Modified by Friction Reforming

Abstract

This research is focused on improving the wear resistance property of stainless steel by using the technique of friction reforming as well as determining the influence of the mated materials. The powder intrusion and friction stir mechanisms are utilized in the surface friction reforming process. Then, wear tests are conducted to examine the wear properties in three different conditions: dry, oil-lubricated, and artificial seawater. Furthermore, investigations of the mated materials are performed. As a result, the modified material presents moderate effects under dry and oil-lubricated conditions. However, in artificial seawater, the modified material exhibits excellent wear resistance properties; the wear volume of the modified material is about one-fourth of that of the substrate material. As for the mated materials, they have a significant influence on the wear properties.
