“…In this way, dry sliding wear behavior for HAMNC1 (5 wt.% of TiO 2 and 5 wt.% of Y 2 O 3 ) was conducted as per Taguchi L 9 OA and results are reported for discussion in Table 5. The correlative tendency of results noticed in the literature where Al composites reinforced with hybrid nanoparticles are greatly influenced by the temperature and sliding velocities 51 . Wear behavior of the material or product has to be very minimal for acquiring maximum lifetime and reliability 42 .…”

This study focuses on the impact of wear process parameters on the sliding wear behavior of titanium oxide (TiO 2 ) and yttrium oxide (Y 2 O 3 ) reinforced pure aluminum (Al) hybrid nanocomposites. The optimization of wear test parameters for hybrid aluminum matrix nanocomposites (HAMNCs) was examined with the design of experiments Taguchi method. The HAMNCs were manufactured by a vacuum die casting technique using a unique double-layer feeding method. Initially, mechanical characterization as tensile and hardness of HAMNC samples was performed to identify the optimum reinforcement. The nanocomposites at 5-wt.% TiO 2 + 5-wt.% Y 2 O 3 (HAMNC1) showed excellent tensile strength and microhardness of 127.6 MPa and 75.43 BHN, respectively, than the other configurations of HAMNCs. The three levels of machine process parameters as load at 5, 10, 15 N, sliding velocity at .5, 1, 1.5 m/s and sliding distance at 200, 400, and 600 m are selected to identify optimum process parameters of HAMNC1 that possess ultimate wear properties. The results derived from optimization were further predicted using ANOVA and regression equations for individual influences. The improved grain size observed in the wear surface morphology of HAMNC1 was performed using field emission scanning electron microscopy.

“…The frictional heat generated will be more, and softening the contact area leads to more wear loss. 90 The different types of reinforcement combinations are used in pursuit to reduce the wear rate. The use of 7.5% B 4 C and 2.5% cow dung ash in Al 7075 matrix decreased wear loss by 59% at higher sliding velocity.…”

Aluminum metal matrix composites are a new class of materials that have gathered more attention from many materialists. Especially, the automotive components like a piston, cylinder block, brake drum, etc., fabricated by different reinforcement, which has exposed better performance over conventional engineering materials. Aluminum composites are generally fabricated by stir casting technique due to simplicity in operation and adaptive to mass or job order production. The paper provides a background for the readers interested in the production of metal matrix composites through stir casting. Based on the literature assessment, the special attentions taken by the researchers to enhance the uniform distribution of particle to avoid agglomeration are discussed. The composite performances mainly depend on the aluminum matrix, particle size, the quantity of reinforcement, preheating temperature of reinforcement, and processing parameters such as stirring speed, stirring time, and wetting agents. The selection of two reinforcements and their suitable parameters for wetting are attaining interest by many researchers and maybe opted as future scope.

“…Tribological tests were performed using a pin-on-disc tribometer as described elsewhere. 25–30 All of the experiments were performed under oil lubricating and laboratory conditions (temperature, T = 25 ℃, relative humidity ∼50%). The lubricating oil used in the test was Shell Rimula R3 Multi 10 W-30 oil and the flow rate was about 2.5 mL/min.…”

In this article, the tribological behaviors of CuPb24Sn under different load and oil lubrication conditions were studied. The worn surface, material transfer, and debris of the material were analyzed by the scanning electron microscopy and energy-dispersive X-ray spectrometer. In addition, the wear rate of CuPb24Sn was measured by means of a laser microscopic 3D and profile measurement apparatus. The results show that the soft phase lead wears preferentially from the sample surface under both light and heavy load conditions. Under the light load condition, the wear rate of the soft phase lead is low. Therefore, in this condition the samples are lubricated by oil and surface residual lead, and the wear mechanism is mainly abrasive wear. However, under heavy load conditions, the soft phase lead is quickly consumed. The lubricating oil film is thinner and the asperities contact is increased. And then the surface temperature and oxidation of samples are increased too. In this case, the main wear mechanisms of samples are adhesive wear and oxidation wear. At the same time, with the depletion of lead, cracks begin to form and propagate at the interface between lead and copper, and then peel off from the matrix to form wear debris, which further accelerates the wear of the sample.
