This paper investigates the mechanical properties and corrosion behavior of Metal Matrix Composites prepared using Al7075 alloy as a matrix, Silicon Carbide and Titanium Carbide as reinforcement particles. Two step stir casting process was used to fabricate the composites by varying volume fractions of Silicon Carbide and Titanium Carbide (0 to 15 vol. %). Microstructural analysis, mechanical and corrosion behavior were used to evaluate the performance of the composites. Uniform distribution of reinforcement particle was observed through optical photomicrographs. Vickers micro hardness tests were performed and the hardness values were increased with an increase in reinforcement from 0 to 15 vol. %. The tensile strength of the 10 vol. % of aluminum hybrid matrix composite was better than that of the base alloy. In 3.5% NaCl solution, it was observed that the 15 vol. % of the aluminum hybrid matrix composite have higher corrosion resistance in comparison the base alloy.

“…A mechanism of new phase creation was presented in [ 32 ]. The influence of new phases on mechanical properties as a result of precipitation hardening and alloying mechanisms is presented in [ 33 , 34 , 35 , 36 ]. However, XRD investigation revealed a tendency to undesired reactions between aluminium and carbon after heating to 1200 °C ( Figure 6 ).…”

In this paper, the applicability of aluminium matrix composites to high-temperature working conditions (not exceeding the Al melting point) was evaluated. The behaviour of Al-Ti-C composites at elevated temperatures was described based on microstructural and phase composition observations for composites heated at temperatures of 540 and 600 °C over differing time intervals from 2 to 72 h. The materials investigated were aluminium matrix composites (AMC) reinforced with a spatial carbon (C) structure covered by a titanium (Ti) layer. This layer protected the carbon surface against contact with the aluminium during processing, protection which was maintained for the material’s lifetime and ensured the required phase compositions of Al4C3 phase limitation and AlTi3 phase creation. It was also proved that heat treatment influenced not only phase compositions but also the microstructure of the material, and, as a consequence, the properties of the composite.

“…The incorporation of TiO 2 particles increases on the surface of matrix alloy, which significantly reduce the plastic deformation because of the TiO 2 reinforcement particles act as an impediment to the moment of displacements, thus giving more wear resistance [23]. At the lower load conditions, it is understood that small shallow grooves, fine scratches occurred at few regions resulting in a lower wear rate and COF due to the restriction of contact between the pin and counter surfaces [26,27].…”

Al7075/10 wt% TiO 2 alloy composite has been fabricated by the stir casting method to investigate the influence of wear parameters. The microstructure of the produced composite was analyzed by scanning electronic microscopy. A pin-on-disc rig was used to carry out the wear test on produced composite under dry sliding conditions. The three wear control parameters such as load, sliding velocity and sliding distance were chosen to study the effects on the wear rate and coefficient of friction of composite. The experiments were planned as per L9 orthogonal array based on Taguchi's design of experiments. The signal-to-noise ratio and analysis of variance techniques were employed to determine the optimum combination of parameters and the significant contribution of each parameter on the responses. The results exposed that the load was the most predominant factor affecting the wear rate and coefficient of friction followed by the sliding distance and sliding velocity. Finally, the regression equations were developed to predict the responses. The worn surface morphology of composite noticed that TiO 2 reinforcement protects the matrix alloy from removal of material at all conditions. This investigation revealed that the wear resistance of the Al7075 alloy can be enhanced by the incorporation of TiO 2 particles.
