摘要

This study examined the tribological behavior of CoCrNi and various textures of CoCrFeMnNi alloys strongly affect their mechanical properties and wear resistance. The focus of this study was put on changes in the material properties of the alloys caused by, surface texturing, with an emphasis on microstructure and mechanical characteristics. The performed experiments included orthogonal array experiments, hardness tests, friction and wear tests, SEM and EDS analyses. Results of the study showed that pits on the surface helped reduce contact area and capture debris, effectively decreasing surface damage under dry friction conditions. Wear mechanisms for the influences of surface texturing on abrasive, adhesive, fatigue, and oxidation wear properties were elucidated. As demonstrated, the surface texturing significantly enhanced the wear resistance of CoCrNi and CoCrFeMnNi alloys.
