“…Additionally, several studies have reported that increasing the rotational speed and the number of passes leads to an ultimate increase in tensile strength. On the other hand, increasing the travelling speed leads to a decrease in the ultimate tensile strength [13][14][15][16][17]. However, an important consideration in surface composite fabrication, aside from the process parameters, is tool wear, which is an undesirable feature and obstacle for the quality of the workpiece.…”

In this paper, optimization of the fabrication parameters of an aluminum surface composite with respect to tensile strength and tool wear rate is reported. The surface layer was reinforced with SiC particles to improve the tribological properties of AA-5052. The Taguchi design with orthogonal array L8 was used for the experimental design, which included three processing parameters: the number of passes, rotational speed, and traversal speed. The experiment used optimal fabrication parameter searching to produce a multi-response prediction of both the tensile strength and tool wear rate. The experimental result was determined by grey relational analysis for multi-performance characteristics. Afterward, the prediction result of the optimal fabrication parameters was confirmed by repeated experiments to confirm the selection of optimal process parameters. The results revealed that the optimal fabrication parameters for multi-performance characteristics are two passes, rotational speed of 1000 revolutions per minute (RPM), and traversal speed of 30 mm/min (condition N2R1T2). These showed high tensile strength (229.90 MPa), low tool wear rate (0.0851), and a uniform distribution of SiC particles in the matrix. In addition, grey relational analysis showed that the parameter priority was 51.68% for rotational speed (the most significant process parameter), 36.18% for transversal speed, and 7.05% for the number of passes. Therefore, the grey-based orthogonal array Taguchi method can optimize multi-performance characteristics through the setting of process parameters for friction stir processing of an aluminum surface composite.

“…Friction stir processing (FSP) was initially derived in 1999 from the work of (Gerlich, 2017;Mishra & Ma, 2005;Mishra et al, 2014) which took its root from a novel technique called friction stir welding (FSW) that was invented in 1991 and patented by the welding institute (TWI) of UK as a solid-state joining method. Afterwards, a large number of research papers have been published for investigating the mechanical properties, microstructure and quality of FSW and FSP components (Narasimharaju & Sankunny 2019;Kundu & Singh 2017;Jian et al 2018;Aliha et al 2016;Taheri-Behrooz et al 2018;Torabi et al 2018;Akbari et al2017Behnagh et al 2012;Shahraki et al 2013;Asadi et al 2012). Since the liberation of FSP in 1999, thousands of articles, hundreds of patents, thousands of textbooks as well as reviewed and peer-reviewed magazines had been in circulation which have been imparting life till date.…”

The efficacy of stainless-steel micro-particles on friction stir processed aluminium-based matrix composite (ABMC) was studied using tribological, mechanical and structural analysis tools. The stainless-steel powder (17-4PH) of average size 45-90 µm was used as the reinforcement particle. The parametric values employed during the fabrication of ABMC-AA7075-T651/17-4PH were the rotational speed of 1500 rpm and travel speed of 20 mm/min while the plunge depth and tilt angles used were respectively 0.3 mm and 3 degrees. Tribological study was carried out under the influence of dry sliding condition with varying loads of 20 N and 50 N using tribometer while the scanning electron microscope (SEM) was used to capture the wear track. Structural analysis was examined with the aid of x-ray diffraction (XRD). The tensile strengths of the fabricated ABMC were also tested and the fracture surfaces were studied using SEM analysis. The results from the study revealed that at higher loading of 50 N, the wear performance was significantly improved for the fabricated aluminium composite-AA7075-T651/17-4PH when compare with lower loading of 20 N. The tensile properties for the ABMC were also improved under the influence of the stainless steel microparticles. There was structural improvement in ABMC wherein the value for crystallite size was lowest while micro-strain, dislocation density, as well as full width at half maximum (FWHM), had the highest values over the FSPed AA7075-T651 and the parent material. The examined fractured surface of the fabricated composite was dominated with fine, network and equiaxed dimples with cup and cone attributes confirming superb interfacial bonding and that the failure mode was ductile.

“…The main microstructural modification takes place in the SZ where the material experiences intense plastic deformation and high temperature causing grain refinement by dynamic recrystallization ( Ref 7). Furthermore, FSP can be used to produce surface composites by incorporating reinforcing particles into the surface ( Ref 2,[8][9][10]. These reinforcement particles are introduced into a hole or groove on the surface, and the rotation of the pin promotes intermixing of particles and the substrate in the near surface layer of the processed metallic substrate.…”

“…Recently, much attention has been paid to the fabrication of Al5083-based surface composites by applying FSP technique ( Ref 4,[8][9][10][11][12][13]. Silicon carbide is one of the most widely used powders to reinforce aluminum alloys because of its low density and high hardness ( Ref 4,[14][15][16][17].…”

In this investigation, nano-sized cerium oxide (CeO 2 ) and silicon carbide (SiC) particles were stirred and mixed into the surface of an Al5083 alloy rolled plate using friction stir processing (FSP) to form a surface nano-composite layer. For this purpose, various volume ratios of the reinforcements either separately or in the combined form were packed into a pre-machined groove on the surface of the plate. Microstructural features, mechanical properties, and corrosion behavior of the resultant surface composites were determined. Microstructural analysis, optical microscopy and scanning electron microscopy, showed that reinforcement particles were fairly dispersed inside the stir zone and grain refinement was gained. Compared with the base alloy, all of the FSP composites showed higher hardness and tensile strength values with the maximum being obtained for the composite containing 100% SiC particles, i.e., Al5083/SiC. The corrosion behavior of the samples was studied by conducting potentiodynamic polarization tests and assessed in terms of corrosion potential, pitting potential, and passivation range. The result shows a significant increase in corrosion resistance of the base alloy; i.e., the longest passivation range when CeO 2 alone was incorporated into the surface by acting as cathodic inhibitors. Composites reinforced with SiC particles exhibited lower pitting resistance due to the formation of microgalvanic couples between cathodic SiC particles and anodic aluminum matrix. The study was aimed to fabricate metal matrix surface composites with improved hardness, tensile strength, and corrosion resistance by the incorporation of CeO 2 and SiC reinforcement particles into the surface of Al5083 base alloy. Optimum mechanical properties and corrosion resistance were obtained for the FSP composite Al5083/(75%CeO 2 + 25%SiC). In this particular FSP composite, hardness and tensile strength were increased by 30, and 14%, respectively, and passivation range was increased to 0.19 V/SCE compared to the base alloy with no passivation range.
