Corrosion protection performance of nano‐particles thin‐films containing vanadium ions formed on aluminium alloys

AbstractWe have developed a new pulsed laser deposition technique using two Nd:YAG laser beams for the nucleation of silicon carbide (SiC) crystalline nano-particles and single crystalline SiC thin films. Transmission electron microscopy and atomic force microscopy observation suggest that several nanometer size SiC particles can be prepared by the new pulsed laser deposition (PLD) method using two Nd:YAG laser beams (1064nm and 532nm). X ray photoelectron spectroscopy measurements suggest that the silicon/carbon composition ratio of the prepared SiC thin films can be controlled by laser fluence and wavelength.

Slurry Erosion

Aluminium alloys are being widely used in naval applications owing to their excellent corrosion resistance and high formability characteristics. One of the most popular naval components is the tarpedo blade which makes use of forged aluminium alloy followed by anodizing surface treatment for corrosion protection. In recent years, there have been few attempts to replace the conventional aluminium alloys by their composites for the tarpedo blade applications. Literature review clearly says that CeO2 (Ceria) coating on aluminium and aluminium composites enhances their corrosion protection in aggressive marine environment. Further, there are reports suggesting that combination of CeO2 and TiO2 do yield better corrosion protection. However, there is no information on the work related to development of hybrid ceramic reinforced aluminium alloy matrices with CeO2 and TiO2 as particulate reinforcements for potential naval applications. In the light of above, the present work focuses on the development of novel Al6061-CeO2-TiO2 hybrid metal matrix composite by stir casting route followed by hot extrusion with an extrusion ratio of 8:1 at a temperature 550 °C and hot forging at 475 °C. The developed forged hybrid composites and the matrix alloy have been evaluated for microstructure, micro hardness and slurry erosion wear tests as per the ASTM Standards.

The semiconductor ZnO has gained great interest in the past decades because of its wide bandgap and large exciton binding energy. Especially, the doping and embedded metal nano-particles methods could improve the conductivity of ZnO thin films, which made it possible to fabricate transparent conducting oxides based on ZnO. In the present study, Al-doped ZnO thin layer was employed to manipulate the electrical and optical properties. The band engineering in ZnO makes it possible to manipulate the absorption, emission, reflection spectral of ZnO via the embedded quantum well layer. The ZnO thin films with excellent performance in electrical conductivity and optical transmittance are promising to be applied in the devices including the lager flat screen, touch panel, portable digital device and smart windows. In the present study, we summarized the recent progress in ZnO with embedded metal nanoparticles and application in TCOs.
