“…Composites in the form of a metal matrix or surface composites show improved mechanical properties. These composites could be manufactured by different approaches such as casting process, mechanical alloying [2], laser sintering methods [3], high-energy electron beam irradiation [4], plasma spraying [5], cast sinter [6] friction stir processing (FSP) [7], etc. However, these methods suffer certain disadvantages like underprivileged interfacial bonding amongst the metal matrix and reinforcement particles, the formation of high strain in the fabricated composite due to crystal structure mismatching, and surface contamination [8].…”

Friction stir processing (FSP) is a novel technique to fabricate metal matrix composites (MMCs) and surface composites (SCs). In the present study, Taguchi's technique is used for attaining the optimum value of microhardness for AA5083/Al-Fe in-situ surface composites (SCs) via FSP using 40 hours mechanical alloyed Fe-40wt% Al powder mixture. Three different process parameters i.e. tool shoulder diameter, tool rotational speed, and tool traverse speed each having three levels were selected for optimizing the microhardness of SCs. The experimental study was accomplished by employing Taguchi's L9 orthogonal array. The Microhardness of the fabricated composites was confirmed using Vickers tester after the single-pass FSP. The outcomes of the study were examined and studied using signal to noise (S/N) ratio. The analysis also confirms the results and displayed that the optimum value of microhardness of 123.3 Hv was obtained with the selected parameter of tool shoulder diameter of 21 mm, tool rotational speed of 900 rpm, and traverse speed of 63 mm/min.

“…Hence to improve the hardness and wear behavior of AA2014 alloy, the production of the surface composite is necessary. The surface composite of AA2014 has been produced by various researchers [9][10][11][12][13] by using different techniques like thermal spraying, cast sinter, laser surface engineering, etc. These techniques have their limitations such as producing high temperatures, and toxic fumes.…”

The present study aimed to improve the micro-hardness and wear properties of AA2014 aluminum alloy. Surface composite of AA2014 was produced using Al 2 O 3 as reinforcement by friction stir processing (FSP) technique. FSP was performed by using a constant traverse speed of 40 mm/min and two rotating speeds of 1000 and 1400 rpm. After FSP, the average grain size of AA2014 was reduced from 21.9 µm in base material to 9.2 µm in FSP with a rotating speed of 1000 rpm and 3.8 µm in FSP with rotating speed of 1400 rpm. Optical microscopy showed that the Al 2 O 3 reinforcement particles were distributed homogeneously in AA2014 after FSP. The micro-hardness test showed that the hardness property in AA2014/Al 2 O 3 surface composite was improved after FSP and was increased with an increase in rotating speed. The micro-hardness was improved by 30% after FSP. The wear test revealed that both the wear performance and coefficient of friction (COF) were improved after FSP. The COF was improved from 0.27461 in base material to 0.22570 in FSPed samples. Surface roughness test showed that the sample with more micro-hardness showed better surface roughness as compared to the other samples.

[16][17][18][19] It has been shown that friction-stir processing (FSP) can be effectively used to homogenise the particle distribution in Al-based in-situ composites. R.

In this study the friction-stir processing (FSP) technique was applied for the development of surface composites of aluminium alloy (AA 1050) reinforced with titanium carbide (TiC) powder of particle size range below 60 μm compressed into the groove. Rotational speeds of 1200 min -1 and 1600 min -1 and the travel rates of (100, 200 and 300) mm/min were used for the process. This study investigates the effect of processing parameters on the wear-resistance behavior of friction-stir processed Al-TiC composites. This was achieved through microstructural characterization using optical and scanning electron (SEM) microscopes equipped with Oxford energy-dispersion spectrometry (EDS) (Tescan), microhardness profiling and wear resistance tests. From the results, it was found that the processing parameters influenced the distribution of the TiC particles. The microhardness profiling of the processed samples revealed an increase in the hardness value compared to the parent material. The wear-resistance test results confirmed the FSP technique enhanced properties in surface engineering. Keywords: aluminium alloy, friction-stir processing, microhardness, microstructure, surface composite, TiC V {tudiji je bila uporabljena tehnika me{anja s trenjem (angl. FSP) za razvoj povr{inskih kompozitov iz aluminijeve zlitine (AA 1050), oja~anih s titanovim karbidom (TiC) v prahu, z velikostjo delcev v obmo~ju pod 60 μm, stisnjenih v utor. Pri tem postopku so bile uporabljene hitrosti vrtenja 1200 min -1 in 1600 min -1 in hitrosti pomikanja (100, 200 in 300) mm/min. [tudija raziskuje vpliv procesnih parametrov na odpornost kompozitov Al-TiCi proti obrabi s trenjem. Izvedena je bila mikrostrukturna karakterizacija z uporabo svetlobnega in vrsti~nega elektronskega mikroskopa (SEM), opremljenega z Oxford energijsko disperzijsko spektrometrijo (EDS) (Tescan), profiliranja mikrotrdote in preizkusa obrabe. Iz rezultatov je bilo ugotovljeno, da so parametri obdelave vplivali na distribucijo TiC delcev. Profiliranje mikrotrdote na vzorcih je pokazalo, da je vrednost trdote pove~ana v primerjavi z osnovnim materialom. Rezultati testa odpornosti obrabe so potrdili, da FSP-tehnika izbolj{a lastnosti povr{ine.
