“…Generally, the effect of graphite depends on the formation of film thickness which in turn depends on many factors that result in graphite extrusion. Hard graphite offers good lubrication at high humidity, high temperature durability, and corrosion resistance against fretting, low friction coefficient under extremely high loads [7]. Molybdenum disulfide is an excellent adhesion property that reduces friction at higher loads, high load carrying capacity, stick slip prevention, fretting corrosion protection etc.…”

The present study is focused on the tribological performance of Molybdenum disulfide (MoS2), and Alumina (Al2O3) used as reinforcement in Al-Si-Mg alloy. By adapting the stir casting route, aluminum matrix composites (AMCs) are manufactured. The process variables such as weight percent of reinforcement i.e., Al2O3 (4,8, 12 and 16 wt. percent ) , and MoS2 (2 and 4 wt. percent), sliding velocity (1 m/s, 1.5 m/s, and 2 m/s), and load (10, 20 and 30 N), on tribological responses are wear rate and coefficient of friction. The experiments are intended to use the Taguchi Orthogonal array (L27). Mechanical properties such as hardness and tensile strength have been evaluated and hybrid metal matrix composites (HMC) have shown significant improvement. Analysis of Variance (ANOVA) revealed wear rate and coefficient of friction decreased with an increase in sliding speed and increased with the applied load. The worn-out, fractured composite surfaces are examined by a scanning electron microscope (SEM). A predominant wear mechanism is observed at low load has a combination of adhesive and abrasive wear, accompanied by high load as adhesive wear. The hybrid composites exhibited improved wear resistance and low friction coefficient as compared to the base alloy.

Al6061-SiC-AlN composites were manufactured using the ultrasonic stir casting method. As reinforcement, silicon carbide and aluminium nitride (both 3 and 6 percent by wt.) were used to provide mechanical properties including tensile, compressive, and hardness. Al6061-SiC-AlN hybrid composite samples' tensile strength, compressive strength, and hardness were measured. Al6061-SiC-AlN hybrid composites' tensile, compressive, and hardness properties are calculated and compared to those of the matrix Al 6061 alloy. The tensile strength, compressive strength, and hardness all rose from 328 to 385 MPa, 145 to 178 MPa, and 302 to 724 VHN, respectively, with the addition of SiC and AlN nanoparticles. The suggested composite is compared to unreinforced Al6061 in terms of density and mechanical qualities such ultimate tensile strength, yield strength, impact strength, hardness, and wear characteristics. The results of the experimental examination showed that the produced hybrid composite, which contains 20% of the total reinforcing material, has no appreciable increase in impact strength but displays high hardness, high yield strength, and low wear rate.

“…At high speeds, the temperature rises faster than the sliding surface, causing the material to oxidize and the material to transfer between the pin and counter face, resulting in the formation of MML. This layer contributes to good tribological properties at high speeds [35][36][37].…”

The current research is concerned with the production of an LM25-FE3O4—Gr metal matrix hybrid composites (MMHCs) and the analysis of its dry sliding wear conditions. The hybrid composites were made out of 3 wt% Fe3O4 and 4 wt% Gr particles with a mesh size of 200 meshes and were made using the stir casting method. Wear test on Taguchi’s L9 orthogonal arrays employs three process parameters: load, sliding velocity, and distance, each changed for three levels on a pin-on-disc tester position. The wear behavior of hybrid composite was investigated using loads of 20 N, 40 N, and 60 N; velocities of 2 m/s, 4 m/s, and 6 m/s; and distances of 1,000 m, 2,000 m, and 3,000 m. The major parameters were developed utilizing the signal-to-noise ratio by selecting “smaller-is-better” wear rates and COF features. FESEM was used to look at the worn surfaces of the composite specimen in order to determine the wear mechanism. Wear properties are enhanced in materials having aluminium hybrid metal matrix composites. According to the ANOVA table, the load parameter has the greatest impact on wear resistance and coefficient of friction, with maximum load values of 35.64 N and 5.782 N, respectively.
