“…The sliding wear response of PRAMCs is affected by many factors associated with the application conditions/testing parameters and nature of the AMCs (i.e. features of reinforcing phases and matrix), which have analytically been reported in previous works [22][23][24]. However, a uniform wear mechanism cannot be established, since a simultaneous contribution of several key factors can lead to severe complexity [25].…”

Aluminum matrix composites were prepared by adding submicron sized WC particles into a melt of Al 1050 under mechanical stirring, with the scope to determine: (a) the most appropriate salt flux amongst KBF 4 , K 2 TiF 6 , K 3 AlF 6 and Na 3 AlF 6 for optimum particle wetting and distribution and (b) the maximum carbide volume fraction (CVF) for optimum response to sliding wear. The nature of the wetting agent notably affected particle incorporation, with K 2 TiF 6 providing the greatest particle insertion. A uniform aluminide (in-situ) and WC (ex-situ) particle distribution was attained. Two different sliding wear mechanisms were identified for low CVFs (≤1.5%), and high CVFs (2.0%), depending on the extent of particle agglomeration.

“…In fact, research conducted over time has shown that the coefficient of friction is not independent of speed and pressure as Coulomb thought [28,29,30] The experimental values obtained lower than the theoretical values are due to the different adherence of the materials in the formation of micro-junctions. In the theoretical model, we taken into account: (a) the mode of processing surface and also (b) the characteristics of the material, but we have not been taken into account the coupling load.…”

-The theoretical and experimental researches on developing of friction coupling materials that are part of the disc-pad braking systems of vehicle and analysis the tribological behavior of them, has been in the spotlight of the specialists in this field in the past decades. Explaining the phenomena that occur at the level of friction surfaces in relative motion have become increasingly complex and often contradictory. Consequently, in this paper was studied the dry sliding wear behavior and friction coefficient evolution of Al-Al2O3-Graphite composite /cast iron system. The proposed theoretical model analyze how the friction coefficient is influenced by different factors as: (a) the adhesion coefficient, (b) the deformation of the material during friction and (c) the inclination angle of the microasperity resulting from the friction process for metal-metal or metal-ceramic coupling in general and aluminum based composite / cast iron couple in particular. For the experimental part we used AlZn6MgCu as aluminium matrix (in cast and age hardening state) reinforced with different proportion of graphite and/ or Al2O3 ceramic particles.The composite samples are tribological tested on cast iron disc (300HB hardness) at room temperature using a pin on disc machine, at contact pressure of 3.5 and 7.5 x 10 -1 MPa and sleeding speed of 3.8 m/s under dry sliding conditions.

“…And finally, there is good compatibility with most practised manufacturing processes like welding, machining, deformation processing etc. [3,9,13,14]. Furthermore, ceramic particles introduced into a metal matrix can greatly enhance the mechanical and tribological properties as well as the anti-corrosion behaviour of such composites [15,16].…”

Microstructure and properties of sintered metal matrix composites reinforced with sic particles Mikrostruktura i właściwości spiekanych kompozytów o osnowie metalowej umacnianych cząstkami sic Abstract Based on the prealloyed and diffusion bonded powders (Distaloy SA and Distaloy SE) different metal matrix composites reinforced with SiC particles were produced by the conventional powder metallurgy technology and the effect of varied amounts of SiC particles on microstructure evaluation and selected properties were investigated. It was stated that the mass fraction of SiC has a great effect on the density, porosity, shrinkage, hardness and wear resistance of studied composites. In the case of both Distaloy SA and Distaloy SE matrix materials, the optimum SiC content is 4 wt. % due to the highest wear resistance and hardness of sintered composite.Keywords: metal matrix composites, SiC particles, Distaloy SA, Distaloy SE, sintering, density, hardness, wear resistance, microstructure Streszczenie Konwencjonalną technologią metalurgii proszków otrzymano z proszków stopowanych i wyżarzanych dyfuzyjnie kompozyty o osnowie metalowej umacniane cząstkami SiC.

Udział masowy cząstek SiC wywiera znaczny wpływ na gęstość, skurcz, twardość, odporność na zużycie ścierne badanych kompozytów. W spiekanych kompozytach o osnowie Distaloy SA, jak i Distaloy SE optymalna zawartość SiC wynosi 4 % wag. ze wzglę-du na najwyższą odporność na zużycie ścieranie i twardość.Słowa kluczowe: kompozyty o osnowie metalowej, cząstki SiC, Distaloy SA, Distaloy SE, spiekanie, gęstość, twardość, odporność na zużycie ścierne, mikrostruktura
