TL;DR: In this article, the performance of AA6082/SiCp composite with multi-pass (one, two and three pass) FSP was investigated, where the influence of multi passes on the microstructure, hardness, surface roughness, phase composition, tensile strength and wear rate were carried out.
Abstract: The uncontrollable wear at the surface of AA6082 against the EN-31 steel has restricted its use in the tribology application. Also, the mechanical properties of AA6082 play a crucial role on the surface wear. So, it is important to improve the mechanical properties to enhance the wear resistance of AA6082. Though, there are several research contributions available for the fabrication of Al/SiCp composite using Friction Stir Processing (FSP), no work pertaining to the AA6082/SiCp composite with multi-pass (one, two and three pass) condition was done earlier. Hence, the present work aims to improve the microstructure, mechanical and wear behavior of AA6082 through surface composite (AA6082/SiCp) fabricated using multi-pass FSP. The influence of multi passes on the microstructure, hardness, surface roughness, phase composition, tensile strength and wear rate are carried out. A significant improvement in the microstructure is achieved for the three pass condition due to the homogeneous distribution of SiCp with reduced particle size evidenced in Transmission Electron Microscope (TEM) analysis. The microhardness of AA6082/SiCp composite increased 2.5 times than the parent AA6082. The strong interfacial bonding between the SiC particle and Al matrix has been achieved for three pass FSPed composite, which is significantly improved the Ultimate Tensile Strength (UTS). The transformation of severe adhesive wear to mild abrasive is observed in a three pass FSPed AA6082/SiCp composite. Wear track characterization is employed using Scanning electron microscope (SEM) to examine the wear mechanism of AA6082 and AA6082/SiCp composites against the EN-31 steel under the dry sliding condition.
