Tribological behavior and mechanical properties of friction stir processed HDPE/Fe-Fe3O4 composites

In the current work, high density polyethylene (HDPE) composites were fabricated via Friction Stir Processing (FSP). A two-phase Fe-Fe3O4 powder was used as reinforcing agents. The extremely low cost obtained from shot-blasting of as-forged carbon steel components. X-ray diffraction (XRD) to phase analysis and evaluation purity as-received powder. size distribution determined by Laser Particle Size Analysis (LPSA). Also, Scanning Electron Microscopy (SEM) employed investigate particles morphology. processing a cylindrical tool impose severe plastic deformation material stirring in order improve mechanical properties distribution. tribological samples examined. According results, both friction coefficient specific wear rate FSPed reduced remarkably. hardness tensile strength higher than HDPE samples; however, their elongations lower.
