“…In addition to this, the Incorporation of ceramic SiC and Kaoline ( Contains Al 2 O 3 , SiO 2 ) into the ductile aluminium matrix and uniform dispersion of these reinforcement particles in the aluminium matrix improves the resistance to the indentation during the hardness test. The obtained hardness values were comparatively higher than the results obtained by the researchers Manikandan et al, [41] and Abhijith Bhowmick et al, [42] in their studies.…”

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.

“…10). This was attributed due to the formation of oxides and gas entrapment during the sintering of composite [27]. In addition to this, at 8% of kaoline reinforcement, more number of kaoline particles undergone sintering and chances of formation of oxides of Si, Al and Ca.…”

“…As the kaoline contains oxides of Al, Si, Ca, Ti, these particles may undergo oxidation during sintering. Moreover, these oxides enhance the contact region between the matrix and reinforcement particles enhances, thereby the presence of void content in the material increases [27][28][29]. indicate that the incorporation of SiC and Kaoline reinforcements strengthen the softer aluminium matrix.…”

In this study, the effect of naturally available and low-cost kaoline particles on the microstructural and mechanical behaviour of Al-SiC-Kaoline Hybrid metal matrix composite was investigated. Al-10% SiC-x% Kaoline (X =0, 2, 4, 6, 8) composite samples were fabricated through powder metallurgy technique by applying a compaction pressure of 350 MPa. The fabricated composite samples were subjected to Density, Hardness, tensile and impact tests to study the mechanical behaviour of fabricated hybrid composite. The presence of SiC and Kaoline reinforcements was confirmed by using SEM and X-Ray Diffraction analysis. It was observed that the maximum ultimate tensile strength (U.T.S) and maximum Yield Strength (Y.S) of the hybrid composite were found to be 263 MPa and 202 MPa for Al-10%SiC-4%kaoline reinforcement. The formation of the intermetallic compound such as Al 2 Cu was observed in XRD and SEM analysis for Al-10% SiC-6 % kaoline and Al-10% SiC-8% of kaoline reinforcement which leads to decrease in the U.T.S and Y.S of fabricated specimens. The impact strength of Al-10%SiC-8% kaoline found to be decreased by 44.4% compared to unreinforced Aluminium due to the presence of harder SiC and Kaoline reinforcements particles. To study the fracture mechanism, Scanning Electron Microscopy study was carried on the fractured Tensile specimens which reveal that ductile fracture in unreinforced Al, Al-10% SiC, Al-10% SiC-2% Kaoline due to the formation of dimples and Brittle fracture was observed in Al-10% SiC-4% Kaoline, Al-10% SiC-6% Kaoline and Al-10% SiC-8% Kaoline due to the existence of cleavages and microcracks.

“…It is also concluded that UTS significantly reduced with enhancing the temperature of casting done and nano particle TiB2 reinforced composite have better ductility in nature as compared as micro particle. Bhowmik et al [22] investigate mechanical properties and fracture behaviour of SiC/TiB2 micro-sized powder reinforced aluminium matrix composite fabricated by stir casting and shown that TiB2 reinforced composite has additional strength related to SiC reinforced composite. Poria et al [23] discussed the wear performance of TiB2 reinforced Al-TiB2 aluminium matrix composite and revealed that wear reduced with incorporation of TiB2 powder.…”

Application of SiC particulate reinforcement impact greatly for making aluminium matrix composite because of its superb heat conductivity, oxidation stability and highly resistance to mechanical erosion. Present work based on dry sliding wear analysis of Al7075/6wt.%SiC composite fabricated by liquid state stir casting method. To acquire a productive wear rate, three major process parameters viz. load, sliding speed and covering sliding distance were compared four different levels. ANOVA analysis showed that the probability rate of load is less than 0.05 that revealed their significant factor. From the study, the highest GRG and GFG values are found 0.914 and 0.854 respectively for the optimal operating parameters of 10 Newton load, 2 metre/second sliding speed and 500 metre sliding distance. Finally, it is revealed that the grey-fuzzy technique effectively authenticate the decision making of wear performance characteristics rather than a plain grey relational grade.
