Abstract

In this study, researchers used powder metallurgy to create a variety of aluminum/boron carbide (Al/B4C) and aluminum/titanium dioxide (Al/TiO2) metal matrix nanocomposites (MMNCs). The manufactured MMNCs were tested to determine their mechanical qualities. In addition, the MMNCs’ corrosion behavior in sodium chloride (NaCl) aqueous solution was studied at varying concentrations of NaCl, temperatures of the solution, and times of exposure. Taguchi’s method for designing experiments was used to create the corrosion tests. Calculations of MMNC corrosion rates (CR) were made in relation to test parameters. Al/TiO2 and Al/B4C MMNCs are shown to have significantly higher hardness than pure Al matrices. The toughness of MMNCs grows as their nanoparticle volume fraction and/or size grows. Corrosion resistance of Al/B4C and Al/TiO2 MMNCs was significantly higher than that of pure Al in NaCl aqueous solution. Corrosion of the Al/TiO2 MMNCs was less rapid than that of the Al/B4C MMNCs. The CR of MMNCs was shown to be primarily influenced by the exposure time and the temperature of the NaCl solution, according to physical and statistical studies.
