“…It is a suitable one for replacing of cast iron engine and improving the vehicle mileage as well as reducing the fuel consumption. In the magnesium material, the wear occurrence takes place in moderate range but addition of reinforced particles is influenced to reduce the wear rate of the magnesium [13][14][15]. Hybrid composites generally possess high wear resistance as well as corrosion resistance even influencing of high performance parameters [16].…”

Magnesium alloy is the light weight material compared to aluminium alloy, and it possesses high strength; these alloys are used to manufacturing of vehicle parts. Magnesium alloy has extreme mechanical and thermal properties, and it is applied to aerospace applications. This study planned to improve the tribological and corrosion resistance of AZ61 magnesium alloy with reinforcement of boron carbide (B4C) and zirconium dioxide (ZrO2). Magnesium alloy hybrid composites are fabricated through stir casting process. Tribological and corrosion performance are analyzed through Taguchi L27 Orthogonal Array. In the tribological analysis, four parameters are involved such as % of reinforcement (4%, 8%, and 12%), disc speed (1 m/s, 2 m/s, and 3 m/s), normal load (30 N, 40 N, and 50 N), and sliding distance (1300 m, 1500 m, and 1700 m). Similarly, in salt spry corrosion analysis, four parameters are influenced used such as % of reinforcement (4%, 8%, and 12%), pH (7, 8, and 9), temperature (30°C, 35°C, and 40°C), and hanging time (30 hrs, 40 hrs, and 50 hrs). From this analysis, percentage of reinforcement is highly influenced in wear test, and in corrosion test, temperature is extremely influenced.

“…From the wear morphology, it can be seen that on the untreated Al-20SiC composite, the wear surface showed a debris-like flaking phenomenon and a certain degree of plastic deformation occurred along the sliding direction on both sides of the plow groove. The stripped SiC constituted abrasive wear during the friction process or entered between the friction subsets, forming scratches and grooves on the wear surface [ 39 ]. At the same time, abrasive wear was further accelerated by the generation of hard particles and adherence to the surface during the sliding wear test, which produced microcuttings in the surface layer.…”

This paper investigates the joint effect of high current pulsed electron beam (HCPEB) and denaturant CeO2 on improving the microstructure and properties of Al-20SiC composites prepared by powder metallurgy. Grazing Incidence X-ray Diffraction (GIXRD) results indicate the selective orientation of aluminum grains, with Al(111) crystal faces showing selective orientation after HCPEB treatment. Casting defects of powder metallurgy were eliminated by the addition of CeO2. Scanning electron microscopy (SEM) results reveal a more uniform distribution of hard points on the surface of HCPEB-treated Al-20SiC-0.3CeO2 composites. Microhardness and wear resistance of the Al-20SiC-0.3CeO2 composites were better than those of the Al matrix without CeO2 addition at the same number of pulses. Sliding friction tests indicate that the improvement of wear resistance is attributed to the uniform dispersion of hard points and the improvement of microstructure on the surface of the matrix after HCPEB irradiation. Overall, this study demonstrates the potential of HCPEB and CeO2 to enhance the performance of Al-20SiC composites.

“…Matrix materials can be enhanced with a hard particulate material to improve their mechanical qualities [5][6][7]. In comparison to steel, aluminium matrix composites (AMCs) are much lighter, cheaper, and provide better mechanical and tribological properties [8][9][10]. Wear control factors were studied in these studies to see their effects on wear rate (i.e., reinforcements, loads, sliding distance, and slipping velocity).…”

This article evaluates the effect of wear parameters on composite materials. Aluminium alloy 7178 alloys with various nano titanium diboride weight percentages were prepared using stir casting. A pin-and-disc test rig was utilized to carry out the dry sliding wear test. Using Taguchi’s experiments for optimization, the L27 orthogonal array was designed (D.O.E.). The SNR and ANOVA techniques were used to identify the percentage of responses attributable to the input parameters. Both the wear rate and coefficient of friction increased with higher loading levels. This parameter, load intensity, had the most significant influence on wear rate and C.O.F. and sliding distance and velocity. Material removal was prevented at all times by nano titanium diboride particles embedded in the matrix alloy. AA7178 was treated with nano titanium diboride particles to improve its wear resistance.
