“…SEM analysis was used to characterize the manufactured composite. The taguchi technique, on the other hand, has been shown by researchers to be an effective tool for composite wear study [24][25][26][27][28][29]. The main goal of this study was to fabricate the hybrid aluminium matrix (HAM) composites (ceramic and inorganic reinforcement) using powder metallurgy (PM) and analyze their mechanical and tribological properties.…”

The study is to investigate the physical, mechanical, and tribological properties of Al6063 alloy reinforced by Silicon Nitride (Si3N4) & compound Copper Nitrate (CuN2O6) processed via Powder Metallurgy (PM) Techniques. Incorporation of reinforcement in matrix material ranged from 6 to 12 % Si3N4 in a 6-step interval, and 2 to 6 %CuN2O6 in a two-step interval. The characterizations were made on the PM produced specimens using OM, EDS, XRD and hardness. The reinforcement particles were distributed uniformly is attributed by homogeneous mixer of matrix and reinforcements. The tests were carried out in accordance with ASTM Standards on the Al6063 alloy and its composites. The test findings show that as the reinforcing percentage of ceramic and inorganic compound is increased, properties such as hardness and density rise monolithically and considerably. The dispersion of Si3N4 and CuN2O6 reinforcement in the AA6061 matrix was ensured by X-ray diffraction patterns. In comparison to the base alloy, the hardness of AA6063/12 %Si3N4/6% CuN2O6 improved by 88 % due to the mismatch of thermal expansion between the Al matrix and reinforcement causes huge internal stress, causing the aluminium matrix to deform plastically to lodge the smaller volume expansion of Si3N4 and CuN2O6 particles. The dry sliding wear test was carried out on a tribometer with a pin-on-disc arrangement, and the findings show that the composite has a higher wear resistance. The Taguchi design of experiments was used to investigate the solution containing parameters employing an orthogonal array, the signal-to-noise ratio, and analysis of variance The weight percentage of Si3N4/CuN2O6 compound and relationship between wt.% of reinforcement and applied load had the highest impact on composite wear resistance, accounted for 31.66 %. Before and after the wear morphology during the wear test, images from a SEM and EDS were used to examine the manufactured composites.

The present research study investigates the Mechanical, Physical, and Tribological properties of powder metallurgy (PM) produced AA6063 alloy reinforced with silicon nitride (Si3N4) and copper nitrate (CuN2O6). Incorporation of Si3N4 & CuN2O6 reinforcement in matrix material ranged from 6 to 12 % Si3N4 in a 6-step interval and 2 to 6 %CuN2O6 in a two-step interval. The characterizations were made on the PM-produced specimens using OM, EDS, XRD, and Hardness. The reinforcement particles were uniformly distributed, which was attributed to a homogeneous mixer of matrix and reinforcements. The test findings show that as the reinforcing percentage of the ceramic and inorganic compound increases, properties such as hardness and density rise considerably and monolithically. The existence of phases such as Si3N4 and CuN2O6 reinforcement in the AA6063 matrix was ensured by X-ray diffraction. The hardness of AA6063/12%Si3N4/6%CuN2O6 increased by 88% over the base alloy due to a mismatch in thermal expansion between the Al matrix and reinforcement, which causes massive internal stress, causing the aluminium matrix to plastically deform to accommodate the reduced volume expansion of Si3N4 and CuN2O6 particles. The dry sliding wear test was determined using the Pin-on-Disc method, and the results show that the composite is more wear-resistant. An orthogonal array and analysis of variance were utilized to evaluate the solution, including parameters using the Taguchi robust design technique. The weight percentage of the Si3N4/CuN2O6 compound and the relationship between weight % of reinforcement and applied load had the most significant impact on composite wear resistance. The produced composite's wear morphology was studied using images from a scanning electron microscope and energy dispersive spectroscopy.

“…An orthogonal array of small trials using the Taguchi technique is a statistical experimentation strategy that provides standard tests a new dimension (Kaushik and Singhal, 2017) (Kumar et al, 2013) wear studies that include variables like load, speed, and sliding distance have used the pin-on-disc approach in large-scale applications. By using an ANOVA, the most significant factor in determining wear characteristics was identified (Kiran et al, 2014) (Asha et al, 2021). According to the literature study, numerous researchers have researched the wear behaviour of MMCs.…”

<p>A large range of engineering applications can be suited to hybrid metal matrix composites because of their improved mechanical properties, making them superior to conventional materials. Hybrid composites are widely used in the automotive and aerospace industries because they feature excellent wear resistance, corrosion resistance, high strength, and low density. This paper demonstrates how to use the stir casting method to create a hybrid composite. The current focus of research is on the fabrication of composites using triple particle silicon carbide (5% weight) and graphite (1.5% weight) as the reinforcements and A357 as the matrix. Wear analysis of the composite materials was conducted following the Taguchi L18 method. To obtain insight into how control factors and heat treatment parameters affect the wear rate of composites, the prescribed number of experiments was carried out. Using ANOVA, major influencing factor for the wear rate accomplished was the sliding distance of all the developed hybrid composites.</p>
