In order to overcome the difficulties of laser melt injection (LMI) on aluminium alloys, the process of tungsten inert gas (TIG) arc enhanced LMI ceramic particles was developed. The influence of process parameters, including laser power, TIG current, the direction of powder feeding, the carrier gas flow of powder and the shield gas flow of TIG, was investigated. The results have shown that to achieve appropriate surface enhancement effect, the powder should be fed from the back side of the laser beam. The depth of the arc enhanced LMI layer increases monotonously with increasing TIG current. The depth of the LMI layer increases first and then decreases with increasing laser power. The carrier gas flow and gas flow of TIG should be matched. Through optimisation of process parameters, WCp/Al layer was prepared successfully on the surface of aluminium alloy. The microstructure of the surface layer prepared by arc enhanced LMI was analysed.

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.

“…ensures considerable enhancement of their mechanical properties. In [ 17 , 18 , 19 ], authors successfully applied hybrid modification with micro- and nanosized particles. When alloyed with dispersed particles, the enhancement of mechanical properties of a metal matrix composite (MMC) is explained by three mechanisms: the Hall–Petch effect (by means of decreasing grain size) [ 20 ]; the Orowan effect [ 21 ]; and reinforcement related to the difference between the thermal expansion coefficients of the matrix materials and reinforcing particles [ 22 ].…”

Machining tools are used in many areas of production. To a considerable extent, the performance characteristics of the tools determine the quality and cost of obtained products. The main materials used for producing machining tools are steel, cemented carbides, ceramics and superhard materials. A promising way to improve the performance characteristics of these materials is to design new nanocomposites based on them. The application of micromechanical modeling during the elaboration of composite materials for machining tools can reduce the financial and time costs for development of new tools, with enhanced performance. This article reviews the main groups of nanocomposites for machining tools and their performance.
