“…In hybrid surface metal matrix composites, wear resistance can be enhanced through the combined effect of stiff ceramic and solid lubricant powder reinforcements. Different investigators explored aluminumbased hybrid surface composites with various arrangements of reinforcement powders [40][41][42][43][44][45][46]. Compared to dry mixing, the solvent-based particle mixing strategy displayed better properties attributed to even mixing and de-agglomeration of particle clusters [44].…”

Aluminum surface composites have gained huge importance in material processing due to their noble tribological characteristics. The reinforcement of solid lubricant particles with hard ceramics further enriches the tribological characteristics of surface composites. In the current study, friction stir processing was chosen to synthesize hybrid surface composites of aluminum containing B 4 C and MoS 2 particles with anticipated improved tribological behavior. B 4 C and MoS 2 powder particles in 87.5: 12.5 ratio were reinforced into the AA6061 by hole and groove method. Microstructural observations indicated that reinforcement particles are well distributed in the matrix. The hardness and wear resistance of hybrid surface composites improved as compared to the base material, due to well distributed abrasive B 4 C and solid lubricant MoS 2 particles in AA6061. The hybrid surface composites achieved~32 % increased average hardness as compared to the base material. Hole method revealed~13 % better wear resistance compared to the groove method for friction stir processed hybrid surface composite, attributing to an improved homogeneity of particle distribution shown by zigzag hole pattern. Moreover, friction stir processed AA6061 without reinforcement particles exhibited reduced hardness and wear resistance due to loss of strengthening precipitates during multi-pass friction stir processing.

“…Despite all fabricating methods available, the Spark plasma sintering technique was adopted due to higher sintering rate, lesser porosity defects and the possibility of obtaining nearly net-shaped products [7,8]. Amra et al, [9] studied the wear and frictional behaviour of Al5083/CeO 2 /SiC HMMC and concluded that minimum wear rate of 4 × 10 − 3 mm 3 /m obtained for Al5083/CeO 2 /SiC HMMC when compared to Al5083/SiC MMC due to the existence of self-lubricating property of the CeO 2 reinforcement particles. Umanath et al, [10] investigated dry sliding wear characteristics of Al6061/ SiC/Al 2 O 3 HMMC against the counter steel disc.…”

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.

In this paper, homogeneously dispersed TiC nanoparticles and fine-grained composite was successfully achieved by friction stir processing (FSP) of in situ 0.5 wt.% TiC/7085Al nanocomposites with different rotational speed. The effects of the rotational speed on the microstructures and tensile properties were investigated. Experimental results showed that the stir zone (SZ) exhibited equiaxed recrystallized grains with fine size and a high fraction of high-angle grain boundaries (HAGBs) caused by dynamic recrystallization (DRX). Moreover, the tensile strength and elongation of the friction stir processed (FSPed) composite were significantly improved compared with the base composite. With the rotational speed of 1000 rpm, the composite has the smallest grain size and the optimum mechanical properties. The average grain size decreased to 1.61 μm, the yield strength (YS), ultimate tensile strength (UTS) and elongation reached to 345 MPa, 429 MPa and 17.8%, respectively.
