摘要：

In the present investigation, SiO2/TiO2/Al5754 alloy hybrid composites were synthesised using vacuum diecasting, and their morphology, mechanical, wear, and corrosion properties were analyzed. The strengthening particles are evenly diffused with Al5754 alloy at 800 degrees C, 650 rpm, and 20 min without residual pores. Due to a reduction in grain size, enhanced wettability, and intrinsic oxidation characteristics, the synthesised immixture exhibits an increase in hardness (32.04 %), tensile (34.6 %), and compressive strength (36.51 %) in context with as cast alloy. The interphase of hybrid blends Al2Si2O7, Mg2Si, and Al2O3 limits oxygen permeability and increases corrosion resistance (40.03 %). By increasing the applied load, the wear loss percentage decreased due to higher stresses and intense plastic deformation at the contact interface.
