Investigation into Mechanical Properties and Sliding Wear Behavior of Friction Stir Processed Surface Composite Material

One of the different and pioneering solid-state techniques, friction stir processing (FSP), is employed for production surface composites. In this research, matrix selected was copper-nickel (CuNi) with hard boron carbide particle as reinforcement. The objective current research work to produce reinforced 90/10 composites B4C fabricated via FSP. influence tool rotational speed on macrostructure, microstructure, grain size analysis, microhardness, wear studies processed (FSPed) CuNi/B4C assessed. For high (1400 rpm) tool, modified area found a maximum 44.4 mm2 uniform dispersion presence in revealed through electron imaging spectroscopic results. Spectra mapping shows distribution over FSPed area, evidence obtained XRD analysis. From experimentation, it interesting report that reinforcements have decreased hardness an increased tool. recorded minimum 223 HV which has gradually 178 1300 rpm. It directly influenced rate FSPed, proportional behavior. worn fractured morphology were also studied using Field Emission Scanning Electron Microscope (FESEM).
