“…9). A similar Al 2 Cu peak was identi ed by the researchers Anbukkarasi R et al, [28], Shakir Gatea et al, [29] and Hailan Ma et al, [30] in their studies. The presence of SiO2 (JCPDS le number 46-1045 [31,32]), Al 2 O 3 (JCPDS le number 00-046-1212 [33]), TiO 2 (JCPDS le number 21-1276 [34]), Cao (JCPDS le number 00-037-1497 [35]) and MgO (JCPDS le number 59-7746 [36]) peaks in the fabricated HMMC were con rmed through XRD analysis.…”

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.

“…4. the identified al 2 Cu peak (jCPdS card no: 25-0012 [27]) was matched with the peak identified by the researcher Gatea et al, [28]. increasing the sintering temperature beyond 550°C accelerates the chemical reactions between the kaolin and aluminium powders and prons to the diffusion of atoms among the adjacent particles.…”

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.
