The manufacturing of nanocrystalline aluminum using mechanical alloying technique after different ball milling times, namely 1, 3, and 5 h was reported. The effect of milling period on the corrosion behavior of the manufactured aluminum in 4.0 wt.% sodium chloride (NaCl) solutions was carried out. The corrosion measurements were studied using potentiodynamic polarization (PP), chronoamperometric current-time at constant potential value (CCT), and electrochemical impedance spectroscopy (EIS) techniques.

A novel attempt is made to study and compare the effects of TiO2 morphology in the form of nanoparticulates and nanofibers on the physical, mechanical and microstructural properties of pure magnesium. Pure magnesium and Mg (1.98 and 2.5) vol. % TiO2 nanocomposites are synthesized by powder metallurgy technique coupled with microwave sintering followed by hot extrusion. X-Ray diffraction studies of the synthesized magnesium materials indicated that morphology of ultrafine reinforcements play a vital role in modifying the strong basal texture of pure magnesium.

The addition of silicon carbide (SiC) nanoparticles into electroless nickel (Ni)-based coatings improves both corrosion resistance and mechanical properties of the resulting Ni-P/SiC nanocomposite coatings, making them potential candidate as protective coatings in aggressive environments. Ni-P/SiC nanocomposite coatings were produced from precursor bath with small SiC loading levels (0.25 or 1.0 g/L) and characterized for morphology, corrosion resistance, and hardness.

Al–TiC nanocomposite materials have been prepared by a new in situ synthesizing technique. A mixture of aluminum, titanium, and graphite has been prepared using ball milling technique and then melted in a high frequency induction heat furnace (HFIHF) at different sintering temperatures, namely 900, 1100, and 1300 ° C. The effect of sintering temperature on the corrosion of the Al–TiC composite in 3.5% NaCl solutions was investigated using cyclic potentiodynamic polarization, chronoamperometric current-time, open-circuit potential, and electrochemical impedance spectroscopy measurements.
