Abstract

In this research, ultrasonic cavitation assisted stir casting was used to nano boron carbide particles (nB4Cp) into the matrix of AA5128 at weight percentages of 0%, 0.6%, 1.2%, 1.8%, 2.4%, and 3.0%. A scanning electron microscope (SEM) was used to analyze the distribution of the reinforcing particles throughout the material. By adding 1.8% nB4Cp, the nanoparticles began to aggregate and no longer distributed uniformly was found. An increase in mechanical characteristics was seen after adding 1.8% nB4Cp, and this increase was followed by a decrease. With only a 1.8% nB4Cp addition, AA5128 is able to boost its tensile strength, micro-hardness, elongation percentage, impact strength and corrosion rate by 189.24%, 49.65%, 50.79%, 74.35%, and 40.16% compared to pure AA5128 alloy, respectively. The addition of only 1.8% nB4Cp has been shown to raise the coefficient of friction by 15.33%, resulting in a 28% increase in wear resistance. The characteristics tend to degrade when more than 1.8% by adding nB4Cp, as the nB4Cp particles begins to cluster, reducing the material’s effective surface area.
