Recently, the attention of scientists has been devoted to improving the various properties of aluminum alloys such as strength, elastic modulus, and wear and corrosion. In this respect, the preparation of hybrid nanocomposites containing two ceramic reinforcements is a promising strategy for enhancing the aformentioned properties for use in various industrial applications. Therefore, powder metallurgy technique was used to manufacture hybrid nanocomposites from Al-Si matrix reinforced with different weight percentages of vanadium carbide (VC) and fly ash (FA) particles. Then, the prepared powders' microstructure and particle size distributions were examined by SEM technique and diffraction particle size analyzer. The prepared powders were sintered in an argon atmosphere and subsequently, their physical, elastic and mechanical properties, and wear and corrosion behavior were measured. The results showed that the addition of 10 wt.% VC and 10 wt.% FA nanoparticles resulted in a decrease in Al-Si alloy particle sizes up to 47.8 nm and improved microhardness yield, strength, and Young's modulus to 161, 145 and 64%, respectively. Also, it remarkably decreased the rate of wear and corrosion to 40 and 67%, respectively.

“…According to the research on the corrosion performance of ceramic reinforced aluminum matrix composites [ 25 , 26 , 27 ], the pores at the interface of the composite are favorable pitting locations. For diamond/aluminum composites, the addition of diamond particles destroys the interface continuity in the matrix.…”

The stability of diamond/aluminum composite is of significant importance for its extensive application. In this paper, the interface of diamond/aluminum composite was modified by adding nanoscale W coating on diamond surface. We evaluated the corrosion rate of nanoscale W-coated and uncoated diamond/aluminum composite by a full immersion test and polarization curve test and clarified the corrosion products and corrosion mechanism of the composite. The introduction of W nanoscale coating effectively reduces the corrosion rate of the diamond/aluminum composite. After corrosion, the bending strength and thermal conductivity of the nanoscale W-coated diamond/aluminum composite are considerably higher than those of the uncoated diamond/aluminum composite. The corrosion loss of the material is mainly related to the hydrolysis of the interface product Al4C3, accompanied by the corrosion of the matrix aluminum. Our work provides guidance for improving the life of electronic devices in corrosive environments.

“…The neutron shielding ability of Al-B 4 C composites depends on the B 4 C content, but the corrosion rate of Al-B 4 C composites is increased with increasing reinforcement contents [12]. Surface chemical treatment, corrosion inhibitor and accumulative roll bonding were used to ameliorate the corrosion performance of Al-B 4 C composites [13][14][15]. Graphene nanoplatelets (GNPs) is a single atomic sheet of carbon with a honeycomb-like structure [16,17].…”

Electrochemical corrosion tests (2500 ppm H 3 BO 3 and 3.5 wt-% NaCl + 2500 ppm H 3 BO 3 solution), salt spray tests and associated microstructure analysis were conducted to investigate the corrosion behaviours of bioinspired Al-xB 4 C-1GNPs laminated composites. The low porosity, defects and tightly bonded interface contribute to the high corrosion resistance. The increase of B 4 C content increased the corrosion potential and decreased the corrosion current density. The Al-5B 4 C-1GNPs has the highest corrosion resistance in NaCl + H 3 BO 3 solution, the corrosion rate is 0.00459 mm/a. The laminated composites have better corrosion resistance in X plane than that in Z plane. The GNPs can prevent the Al matrix underneath it from contacting with solution and O 2 . The laminated structure and orientation of GNPs can effectively change the corrosion pathway and prevent the corrosion crack propagating longitudinally into the composite.
