“…7. results reveal that with the incorporation of kaolin particles from 2 wt % to 4 wt %, the u.t.S was improved from 102 mPa to 136 mPa due to the availability of harder Sio 2 and al 2 o 3 compounds in the kaolin reinforcement [25,32]. Beyond the incorporation of 4 wt % kaolin particles leads to decrement in u.t.S due to the formation of agglomerations at the interfacial regions.…”

the present research addresses the low-temperature sintering of 4% kaolin clay reinforced aluminium composite using susceptor-aided microwave sintering at 2.45 Ghz frequency. kaoline clay the naturally available mineral in the north-eastern regions of india. the study aims to convert this kaoline clay into the value added product with enhanced mechanical properties. the al-x% kaolin (x = 2, 4, 6, 8, 10) composite was fabricated through the powder metallurgy process by the application of 600 mPa compaction pressure. the composite corresponding to optimum ultimate tensile strength (u.t.S) was subjected to single-mode cavity microwave-assisted sintering by varying the sintering temperatures as 500°C, 550°C and 600°C. the effect of incorporating kaolin clay on the dielectric characteristics of composite powders, as well as the effect of sintering temperature on the microstructural changes and mechanical characteristics of al-4%kaolin composites were also examined. results concluded that the addition of 4 wt% kaolin powder improves the dielectric characteristics of the composite powder. the maximum hardness. Compression strength and u.t.S of 97 hv, 202 mPa and 152 mPa respectively achieved for the al-4% kaolin composite sintered at 550°C. the higher fracture toughness of 9.56 ma. m 1/2 reveals the ductile fracture for the composite sintered at 550°C.

“…Ball milling was performed in RESTECH 100 planetary ball mill at a speed of 300 rpm for 3 h to disperse the reinforcements uniformly throughout the matrix and to induce the strain hardening effect in the powder particles. The entire ball milling setup was sealed with inert gas (Ar) atmosphere to prevent the contamination and oxidation of aluminium powder during the milling process [21,22]. These milled powders were charged into a graphite die and subjected to the simultaneous application of 35 MPa pressure and 2 KW power supply by using an automated SPS machine (FCT syateme, HP D-5 type, Rauenstein, Germany) [23].…”

In this present study Al-10% SiC- X % Kaoline (X= 0, 2, 4, 6, 8) HMMC synthesized by spark plasma sintering technique. The fabricated HMMC samples corresponding to maximum compression strength was subjected to tribological investigation under dry, oil and nanofluids lubricating conditions. Nanofluid lubricants were developed by incorporating SiC nanoparticles with weight percentages of 1 wt%, 1.5 wt% and 2 wt% into the soluble oil. The thermal conductivity was found to be increased with increasing the wt % of SiC nanoparticles and the maximum thermal conductivity of 0.771 W/m.K was obtained for the nanofluids with 2 wt% SiC nanofluids. Sliding wear test was conducted on the pin-on-disc tribometer at 40 N load and sliding speed of 1500 r.p.m for a sliding of 180 s. Results reveal that there was a significant effect of the lubricating conditions (dry, oil and nanofluids) on the wear and C.O.F of the HMMC pin surface. The minimum wear of 119 microns and minimum C.O.F of 0.11 was obtained for nanofluid with 2 wt% SiC nanofluid lubricating conditions. SEM analysis of worn surface under dry and soluble oil lubricating conditions reveal the presence of microcracks and delaminations wear. However, worn surface with smooth grooves and absence of microcracks was identified under nanofluid lubricating conditions.

“…But in the MaS process, the internal heat generation from the particle leads to uniform heat dispersion and the initiation of strong bonds among the adjacent particles. researchers develop the metal matrix composites by reinforcing naturally available particles such as coconut shell ash, cow dung powder, aloe vera particles and rice husk to enhance the mechanical characteristics of the composite [5][6][7]. Manikandan et al, [7] analyzed the stir-casted al-Cowdung-B 4 C composite and concluded that the presence of self-lubrication property of the cow dung particles decreases the hardness of the fabricated composites up to the addition of 10% cow dung particles.…”

CharaCterization of MiCrowave Sintered aluMiniuM CoMpoSite reinforCedwith hydroxyapatite extraCted froM rihu fiSh SCaleS in this study, hydroxyapatite (hap) is extracted from the rihu fish scales which are generally dumped as garbage. the aluminium composite was fabricated through the powder metallurgy technique by reinforcing hap (0, 5, 10 and 15 wt%) as a reinforcement. The fabricated samples were sintered through microwave sintering at 530℃ for 15 min under an argon gas environment. the fabricated composites were subjected to X-ray diffraction (Xrd), Scanning electron Microscopy (SeM) and energy dispersive Spectroscopy (edS) analysis to confirm the constituting elements and to describe the reinforcement dispersion in the matrix. Uniform reinforcement dispersion was observed for the composite reinforces with 5%hap, 10%hap particles. the mechanical characterization results reveal that the al-10% hap composite exhibits a microhardness value of 123 ± 3 hv and maximum ultimate tensile strength of 263 ± 10 Mpa and 299 ± 9 Mpa compression strength was obtained due to the presence of a strong bond among the aluminium and hap particles.
