“…The hardness and wear resistance were analyzed in surface composite of A380-SiC using FSP route. The optimum values of hardness (177 Hv) at 1460 tool rpm during FSP-ed surface composite and wear rate (4x10-8 gm/cm) was noted at 15 N loading conditions as concluded by Maryam and Akeel 21) . To the authors knowledge, few reports are explored to fabricate the Al6063/graphene nano powder SCs using FSP technique.…”

Surface Composites (ASCs) fabricated using Friction Stir Processing (FSP), which enhances the hardness and tensile strength prodigiously appropriate for automotive applications, for example, piston skirts in the cylinder chamber. This covers the way for the examination of multi-pass impacts of graphene nano-powder filled in Al-6063 SCs for investigation of microstructure, hardness, tensile strength, and grain size. The microstructural analysis uncovers the homogenous dispersion of graphene nano-powder particulates in the Al-6063 alloy, and on escalating the numbers of passes during FSP, uniform dispersion of graphene nano-powder in matrix material was observed due to a reduction of grain size in the produced Aluminum metal matrix composites (AMMCs). The results revealed that the superior microhardness of 106.4 VHN along with maximum tensile strength (217 ± 2 MPa) is achieved after the third pass of the tool. The minimum grain size of 23 µm was also observed in 3P-FSP-ed ASCs during friction stir processing.

“…FSP technology is also successfully used to eliminate defects and material loss in the sample [ 14 ] and to produce surface composites [ 15 , 16 , 17 ] or to modify the microstructure of composites [ 18 , 19 ]. The production of surface composites consists in introducing the reinforcing phase in the form of particles [ 20 , 21 , 22 ] or fibers [ 23 ] into the plasticized matrix. Currently, there are a number of solutions and methods allowing effective introduction of the reinforcing phase during FSP and the production of a surface composite [ 24 ].…”

A rolled plate of 7075 aluminum alloy was friction-stir-processed (FSP) with simultaneous cooling by an air stream cooled to −11 °C with a jet cooling nozzle. Two variants of air blowing were used: at an angle of 45° to the sample surface and at an angle of 90°. The reference material was a sample subjected to analogous treatment but naturally cooled in still air. The microstructural tests revealed strong grain refinement in all the samples, with higher grain refinement obtained in the air-cooled friction-stir-processed samples. For the naturally cooled samples, the average grain size in the near-surface area was 7.6 µm, while for the air-cooled sample, it was 1.4 µm for the 45° airflow variant and 3.2 µm for the 90° airflow variant. A consequence of the greater grain refinement was that the hardness of the air-cooled friction-stir-processed samples was higher than that of the naturally cooled samples. The improvement in abrasive wear resistance was achieved only in the case of the friction-stir-processed specimens with air cooling. It was found that the change in the air blowing angle affects not only the degree of grain refinement in the stirring zone, but also the geometrical structure of the surface. In all the samples, FSP caused redistribution of the intermetallic precipitates combined with their partial dissolution in the matrix.

“…Additionally, the decrease in hardness below the base metal value was less present on the retreating side. Such non-symmetrical behavior can mostly be attributed to the temperature increase in the advancing side in comparison to the retreating side during processing, as reported by [40,41]. The hardness profile recorded for the workpiece processed with a plunge depth of 0.6 mm was reported by Sharma et al [26], indicating steep fluctuations in the hardness values from the center towards the composite/matrix interface.…”

A New Approach to Direct Friction Stir Processing for Fabricating Surface Composites

Friction stir processing (FSP) is a green fabrication technique that has been effectively adopted in various engineering applications. One of the promising advantages of FSP is its applicability in the development of surface composites. In the current work, a new approach for direct friction stir processing is considered for the surface fabrication of aluminum-based composites reinforced with micro-sized silicon carbide particles (SiC), eliminating the prolonged preprocessing stages of preparing the sample and filling the holes of grooves. The proposed design of the FSP tool consists of two parts: an inner-threaded hollow cylindrical body; and a pin-less hollow shoulder. The design is examined with respect to three important tool processing parameters: the tilt angle of the tool, the tool’s dispersing hole, and the tool’s plunge depth. The current study shows that the use of a dispersing hole with a diameter of 6 mm of and a plunge depth of 0.6 mm, in combination with a tilting angle of 7°, results in sufficient mixing of the enforcement particles in the aluminum matrix, while still maintaining uniformity in the thickness of the composite layer. Metallographic examination of the Al/SiC surface composite demonstrates a uniform distribution of the Si particles and excellent adherence to the aluminum substrate. Microhardness measurements also show a remarkable increase, from 38.5 Hv at the base metal to a maximum value of 78 Hv in the processed matrix in the surface composites layer. The effect of the processing parameters was also studied, and its consequences with respect to the surface composites are discussed.
