    Recent advances in aluminizing of mild steel plates
    (Elsevier, 2024) Huilgol, P.; Bhat Panemangalore, D.; Bhat, K.U.; Bharadishettar, N.
    Aluminizing of steels is a surface modification method wherein the steel surface is subjected to thermo-chemical diffusion treatment at temperatures in the range of 700–1000°C. During the treatment, aluminium will diffuse into the surface and subsurface of the steel substrate, producing various aluminide phases. By controlling the process parameters, the type and quantity of aluminide phases can be controlled. The aluminides present beneficial properties, like increased strength and hardness, oxidation resistance, erosion resistance, abrasion resistance, etc. Hence, they are a better candidate material for designing the materials against scratch, erosion, fatigue, wear, oxidation, and corrosion. Many processing routes are available for aluminizing of steels and this entry reviews recent developments in the aluminising of mild steels. © 2024 Elsevier Ltd.

    Fabrication and performance evaluation of hybrid supercapacitor electrodes based on carbon nanotubes and sputtered TiO2
    (Institute of Physics Publishing michael.roberts@iop.org, 2016) Aravinda, L.S.; Nagaraja, K.K.; Nagaraja, H.S.; Bhat, K.U.; Badekai Ramachandra, B.R.
    We report a simple and eco-friendly method for the fabrication of a titanium dioxide/functionalized multiwalled carbon nanotube (TiO2/FMWCNT) composite electrode for use in supercapacitors. The nanocomposite electrodes were formed by depositing titanium dioxide onto FMWCNTs using reactive magnetron sputtering, thus providing a green roue for the formation of the binder-free composite electrode. It is shown that the electrochemical performance of the fabricated electrodes can be altered by tuning the thickness of the titanium dioxide overlayer. The integrated nanocomposite electrode showed an improved specific capacitance of 90 Fg-1 in two-electrode configuration. © 2016 IOP Publishing Ltd.
