Influences of tool velocity ratio on wear behavior of friction stir processed LM25AA-5%SiCp metal matrix composites

Several scientists reviewed the influence of the rotation speed and the transverse velocity of devices with friction stir composite processing (FSP) properties. Results proved that significant microstructural changes were affected by altering these parameters. However, the effect of rotation speed and traverse speed of tool has been less explored. Furthermore, no efforts have been made to investigate the consequence of tool velocity ratio so far to wear the aluminum-based metal matrix composites treated with friction stir processed. Therefore, an effort was made in this research to investigate the actuation of the tool speed ratio on the characteristics of aluminum-SiCp composite processed in friction stir processing. Rotational speed and traverse speed of tools selected. In accord to an optimized working range and the corresponding tool velocity ratios were calculated. The FSPed region's morphology, and wear rate were associated with the corresponding tool velocity ratios. It has been identified from this investigation that the device tool velocity of 2.60 resulted in the FSP region with superior resistance to wear compared to other tools velocity ratios. © 2020 Elsevier Ltd
