Abstract In this study, the surface microhardness, friction and wear performance of recycled aluminium alloy 6063 were improved via an energy-efficient surface engineering technique known as friction stir processing. Different tool rotational speeds of 1200 rpm, 1400 rpm, 1600 rpm, 1800 rpm and 2000 rpm with a fixed feed rate of 30 mm/min were used to process the recycled aluminium alloy 6063. The effects of rotational speed on the microstructure, surface microhardness and tribological performance of the samples were analyzed. The results show that the samples produced at a stirring speed of 1200 rpm achieved the greatest enhancement of 25 % in surface microhardness, 37 % in wear resistance and 33 % reduction in friction coefficient. This has significant implications for environmental sustainability as a relatively low rotational speed, hence a low energy input, is sufficient to enhance the surface properties of recycled aluminium alloy 6063. The benefits of superior tribological properties of recycled aluminium alloy afforded by such an energy-efficient surface engineering method include reduced exploitation of new resources, reduced carbon footprint, and enhanced product sustainability and durability.

FSP (friction stir processing) technology is a modern grain refinement method that is setting new trends in surface engineering. This technology is used not only to modify the microstructure of the surface layer of engineering materials, but increasingly more often also to produce surface composites. The application potential of FSP technology lies in its simplicity and speed of processing and in the wide range of materials that can be used as reinforcement in the composite. There are a number of solutions enabling the effective and controlled introduction of the reinforcing phase into the plasticized matrix and the production of the composite microstructure in it. The most important of them are the groove and hole methods, as well as direct friction stir processing. This review article discusses the main and less frequently used methods of producing surface composites using friction stir processing, indicates the main advantages, disadvantages and application limitations of the individual solutions, in addition to potential difficulties in effective processing. This information can be helpful in choosing a solution for a specific application.

Friction stir processing (FSP) is emerging as a singular solid-state surface engineering technique to fabricate surface composites (SC) since its adaption from Friction Stir Welding (FSW) from the early 90s. FSP is a promising technique to overcome the barrier of magnesium being a poor material in terms of wear and corrosion resistant without adding much on the processing cost and thus, widen its applications.The targeted property enhancement by forming surface composites via FSP are strength, ductility, hardness, wear resistance, toughness, fatigue life, formability, corrosion resistance, etc. Although, a decade of research work has been carried out on FSP for different metal alloys, the advantages of the process particularly on magnesium alloys is yet to be understood clearly. The present review is focused on understanding the response of magnesium alloys for friction stir processing to fabricate surface composites. The available literatures have been thoroughly reviewed to present the microstructure evolution during processing and the mechanism of strengthening; the works on magnesium has been summarized to understand the effect of various processing parameters such as tool speed (rotation and traverse), number of passes, etc. and the tool geometry on the resulting properties. Also, details regarding the selection of suitable tool material and reinforcing particles to achieve optimum properties for specific magnesium alloys is included. Important suggestions and scope for further research regarding fabrication of surface composites on magnesium alloy are provided.

The contemporary trend of cost-saving is the primary motive while studying the relative motion between the material surfaces. Therefore, exceptional surface characteristics are the most desirable features for any material. The rapid emerging surface modification phenomena like Friction Stir Processing (FSP) have proved its potential in the surface engineering applications. In this study, Magnesium–Aluminum–Silicon (Mg–Al–Si)-based AS21A magnesium alloy was examined for the wear characterization in respect with the cast and Friction Stir Processed (FSPed) conditions. FSP, performed at an optimized set of parameters, was utilized to attain the surface modification in the investigated material. In the wear study, cast and FSPed conditions of AS21A specimens were examined on Pin-on-disc apparatus with typical load values ranging from 10–40[Formula: see text]N. The subsequent investigation involves characterization of worn surfaces through Scanning Electron Microscope (SEM) micrographs, and Energy Dispersive X-Ray Spectrometer (EDS) to understand the accountable wear mechanism. It was found that the FSPed AS21A samples exhibited noteworthy improvement in the wear characteristics at all assessment conditions. FSPed sample showed overall 17% enhancement in the specific wear rate. Also, with an increase in normal load, around 53–55% reduction was observed in the Coefficient of Friction (COF) value. It was established that the morphology of Mg2Si precipitates had an active contribution in the wear behavior of cast and FSPed AS21A samples. The notable mechanisms found responsible for the wear of samples were adhesion, abrasion, oxidation, delamination and plastic deformation.

Aluminum based metal matrix composites are given more attention in fabrication of surface engineering applications due to their excellent mechanical and wear properties. In this study, Friction stir processing (FSP) method was used to fabricate the surface composite with inserting different volume % of ZrO2 reinforcement particles in the Aluminum 6082 alloy. The hardness and triblogical characteristics of fabricated surface composites and base alloy were investigated. The higher volume content of reinforcement surface revealed higher hardness and higher wear resistance compared to the lower volume content reinforcement surface and base material. The wear worn-out of composite surfaces and base alloy were examined through SEM for understanding the wear mechanisms.

Aluminum alloys would have much wider usage in bearing applications if their wear-resistance could be significantly improved. This investigation developed a solid-state surface engineering process to form an aluminum-alumina composite surface by friction stirring ceramic particles into an aluminum surface to improve the surface hardness and wear-resistance without sacrificing the bulk ductility and conductivity. Composite layers have been successfully processed on pure aluminum (Al 1100) surfaces that have a relatively uniform particle distribution with a concentration up to 25 vol% of alumina. Microscopic examination showed that particles were severely fractured during friction stir processing and, accordingly, the particle size decreased from the original 10–50 μm to 1–5 μm in the friction stir processed composite layer. The microindentation hardness of the aluminum surface was increased from 0.33 to 0.70 GPa (HV) and the wear-resistance was improved by 30X when rubbing against a bearing steel. It has been demonstrated that powder placement methods and process parameters can be tailored to improve particle dispersion and surface hardness. Unlike most other surface engineering techniques, this process can form very thick layers, up to centimeters in thickness, avoiding delamination because of the inherent material continuity.
