Dissertation note: Thesis (M.Sc.) - Cairo University - Faculty of Science - Department of Physical Chemistry Summary: Nanocomposites of graphene nanosheets anatase titanium dioxide (GNS - TiO₂) were prepared via hydrothermal method and characterized using different methods. The fabricated GNS-TiO₂ nanocomposite was co - deposited with Ni by 2 electrodeposition technique and used as a protective film for mild steel used in the construction of steel silos. The Ni - GNS - TiO₂ nanocomposite coatings were 2 characterized using FE - SEM and EDX. The Ni - GNS - TiO₂ nanocomposite 2 coatings were subjected to electrochemical tests in NaCl, citric acid and acetic acid, in addition to mechanical test. It was found that the incorporation of GNS- TiO with Ni matrix increases the hardness and decreases the corrosion rate. The 2 best corrosion resistance value of 33.1 K{u2126} cm2 and relatively high hardness value of 478 HV were recorded for the composite coating electrode that contains 20.4 wt. % GNS - TiO compared with the other composite coating electrodes or 2 pure Ni coatings
