Tribological and corrosion behavior of electrochemically deposited Co/TiO2 micro/nano-composite coatings

Co/TiO2 micro- and nano-composite coatings having different amounts of reinforcing particles were electrochemically deposited on st37 steel sheets, and their characteristics, tribological properties, and corrosion behavior were compared. With a relatively similar hcp structure, the nano-composite coatings had a nodular morphology which was different than the relatively smooth morphology of pure cobalt and micro-composites. The hardest and the...
