Aug 14, 2020 · The goals of this investigation are the optimization and characterization of Al6061/Al 2 O 3 nanocomposite, which was synthesized by stir casting technique. Different concentrations of Al 2 O 3 nanoparticles as 5, 10, and 15 wt% with an average particle size of 40 nm were examined. The alumina nanoparticles were critically refined and distributed homogeneously in the Al6061 matrix. Effect of Load on the Tribological Properties of Eutectic Feb 07, 2020 · Abstract. Advanced composites are the materials of the new generation. Hence, the focus of the study is to determine the tribological properties of the eutectic Al-Si alloy reinforced with (2, 4, 6, 8, and10 wt. %) of n-Al 2 O 3 against chrome-plated steel ball under dry sliding conditions. The novelty of this work is the fabrication of the composite sample with this elemental composition
Jan 01, 2020 · Al 2 O 3 content is fixed as 1 wt% and SiC content is varied from (0, 2, 4, 6, and 8) wt.% as reinforcement materials. Microstructure, mechanical properties and wear behaviour of prepared samples have been investigated. The result indicates that incorporation of Al 2 O 3 and SiC reinforcements in aluminium Al-6103 grade matrix improved hardness and wear resistance of the material. 8 wt% SiC and 1 wt% of Al 2 O 3 Microstructural analysis and tribological behavior of Oct 20, 2014 · The composite with 10% Al 2 O 3 and 5% nanographite showed the best tribological properties. Overall results indicated a positive response of metal-ceramic hybrid composite for wear resistance and light weight applications, mainly in the field of aerospace and automobile sectors. Microstructural and Tribological Investigation of High Mar 01, 2009 · Their structural and microstructural characteristics, micromechanical behavior, and tribological properties were studied and compared to conventional atmospheric plasma sprayed and high-velocity oxygen-fuel-sprayed Al 2 O 3 coatings manufactured using commercially available feedstock. The HVSFS process enables near full melting of the nanopowder particles, resulting in very
In the present study, the effect of the Al2O3 particles (average size of 12 lm, 3 and 10 wt.%) reinforcement on the microstructure and tribological properties of Al-Si alloy (A356) was investigated. Microstructural and tribological properties of A356 based Oct 03, 2018 · It seems that the Al 2 O 3 particles are agglomerated lesser than the Gr particles. This can be attributed that the Gr particles, as lubricant, is softer than the Al 2 O 3 particles and it does not have thermal expansion coefficient rather than the Al 2 O 3 particles. On Investigating the Microstructural, Mechanical, and Jan 01, 2021 · et al.  created a model of the fatigue limit stress of different composites reinforced with carbon bers and silicon carbide. Our research focused on analyzing the microstructural, mechanical, and tribological properties of FeGr1-based sintered MMCs with the single and hybrid addition of a silicon carbide and graphite.
Dec 25, 2020 · The presence of -Al 2 O 3 in SPS coatings (equal to 39 vol% for KK_C_1, 44 vol% for KK_C_2, 58 vol% for KK_HM_1 and 62 vol% for KK_HM_2) resulted from the unmelted -Al 2 O 3 feedstock particles (confirmed by microstructural investigations).
