In automotive and aircraft design, a new emerging material known as AA8011 metal matrix composite has earned a place for the reason that it is extremely durable and extremely hard. Newer composite variants were created and selected because of the demand for improved tribological performance. This study’s objective is to find out how an AA8011‐Boron Nitride metal matrix composite (MMC) wears out under different loads and sliding speeds. AMMC fortified with Boron Nitride particles are created using the powder metallurgy route and contain weight fractions ranging from 10% to 15% of the AA8011 and 37 μm Boron Nitride particles. The material is made in an electric melting furnace through a stir casting procedure. Next, the materials are tested to see how long they will last in a tribotester set up like this: a block on a roller. With a controlled experimentation strategy, wear data can be collected using the L27 Taguchi method. Dry sliding wear of composites is controlled by four parameters: Boron Nitride substance, load‐bearing capacity, slid speed, and sliding time. An analysis of variance is used to determine their effects. Sliding speed, friction, and normal load all have an effect on how much dry sliding wear occurs. In addition, the least amount of wear is obtained by combining the four controlling parameters optimally.

This study reports on the silicon photovoltaic cells with such an alumina metallization. The photovoltaic cell’s silicon component was subjected to an effective stress studied using a simulation model built with this information. In order to evaluate the efficiency of photovoltaic cells on both sides, as well as in two distinct orientations, a four-point bending experiment analysis was carried out using the model. The side and direction of loading have a significant impact on both strength and fracture. There is tensile stress going perpendicularly along the busbars; the back side of the test specimen had the lowest measured strength.

In this study, the influence of zirconium dioxide (ZrO₂) and graphite (Gr) on the mechanical behavior and characterization of Hybrid metal matrix composites (HMMCs) is investigated. By using the stir casting method, the samples are prepared with aluminum alloy (AA7475) as matrix and 2, 3, and 4 weight percentages (wt%) of zirconium dioxide (ZrO₂) and graphite (Gr) as reinforcements. The synthesized composites were subjected to microstructural, density, porosity, yield strength (YS), ultimate tensile strength (UTS), and hardness were examined. Microstructural characteristics were examined using scanning electron microscopy (SEM). The XRD pattern indicated the presence of the ZrO₂ and Gr phases in HMM composites. By conducting a corrosion resistance test, the rate of corrosion for the HMMCs was determined. Furthermore, the Tafel plot curve was employed to probe the level of corrosion resistance. With an increase in ZrO₂ the corrosion resistance increases whereas decline in ductility is noted. The HMMCs 3 sample exhibit superior physical and mechanical properties when compared to other HMMCs and base matrix. Tensile fractography was carried out to determine the various fracture mechanisms.
