Al–Si alloys are commonly utilized in the production of automobile components, including pistons and cylinders. Although this alloy offers desirable features for usage in pistons, several microstructural characteristics, such as the presence of needle-like silicones or dendrites, impair the performance of the parts produced. In this study, TiC reinforcement particulates were employed to generate matrix composites via friction stir processing (FSP) to increase the wear resistance of Al–Si alloys. The microstructural characteristics of the nugget zone of FSPed specimens were studied. The results reveal that the FSP improves the base alloy microstructural characteristics. The particle distribution and quality of the bonding between the TiC particles and the aluminum matrix were investigated using SEM. The hardness and wear tests were performed to establish the mechanical and wear properties of the particle reinforced composites. The hardness test results showed that the produced composites had a hardness of 144[Formula: see text]HV, which shows a growth of almost 220% compared to the base metal. The pin-on-disc wear test was carried out with sliding speeds of 1 and 2[Formula: see text]m/s, and loads of 5, 10 and 20[Formula: see text]N. The wear test results showed that the wear resistance of the produced particle-reinforced composite compared to the base alloy was improved by about 540%.
<p>Air pressure systems play an essential role in Scania trucks, so that the correct operation of the braking system and gear shifting system of Scania cars depends on the health of the air pressure system. The presence of the central control unit (ECU) in the air pressure system has caused the collection of different information about its different status, which can be stored and checked in the form of different data sets.</p>
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
