Abstract

The imperative to produce lightweight-components has intensified the need for fabrication of Mg-matrix composites. This investigation addresses this exigency by using friction stir processing (FSP) as a solid-state route. This study's goal was to find out how vibration affects the tribological and mechanical properties of AZ31/CeO₂+h-BN surface composites that were made using FSP and FSVP. The attained data showed that FSVP resulted in better homogeneity of CeO₂+h-BN particles across the matrix. The findings also showed that adding vibration to FSP leads to improved hardness and increased shear punch strength (SPT), but also leads to higher wear resistance. The 43 % reduction in grain size in FSVPed composites resulted in a 16 % increase in hardness, while the SPT also improved by approximately 33 %. These changes also resulted in a 25 % decrease in wear rate and a 25 % reduction in average friction coefficient for FSVP composites compared to the FSP. These results suggest that FSVP had a great potential in the mechanical and tribological properties enhancement of AZ31Mg alloy composites.

期刊介绍： Vacuum is an international rapid publications journal with a focus on short communication. All papers are peer-reviewed, with the review process for short communication geared towards very fast turnaround times. The journal also published full research papers, thematic issues and selected papers from leading conferences. A report in Vacuum should represent a major advance in an area that involves a controlled environment at pressures of one atmosphere or below. The scope of the journal includes: 1. Vacuum; original developments in vacuum pumping and instrumentation, vacuum measurement, vacuum gas dynamics, gas-surface interactions, surface treatment for UHV applications and low outgassing, vacuum melting, sintering, and vacuum metrology. Technology and solutions for large-scale facilities (e.g., particle accelerators and fusion devices). New instrumentation ( e.g., detectors and electron microscopes). 2. Plasma science; advances in PVD, CVD, plasma-assisted CVD, ion sources, deposition processes and analysis. 3. Surface science; surface engineering, surface chemistry, surface analysis, crystal growth, ion-surface interactions and etching, nanometer-scale processing, surface modification. 4. Materials science; novel functional or structural materials. Metals, ceramics, and polymers. Experiments, simulations, and modelling for understanding structure-property relationships. Thin films and coatings. Nanostructures and ion implantation.
