摘要: Abstract Enhancing the copper-based composites with oxide nanoparticles attracts more attention and many routes are proposed. In this investigation, stoichiometric Cu–TiO2 nanocomposite is synthesized through self-propagating high-temperature synthesis, effect of additional Cu contents 10, 20, 30 wt% on mechanical physical features composite was evaluated. To investigate obtained properties specimens, scanning electron microscopy, X-ray diffractometry (XRD), micro-hardness, electrochemical impedance spectrometry polarization tests were carried out. XRD results show that metastable phase formed within synthesis. With increasing content, amount reduced. The maximum Vickers micro-hardness 369 HV for sample, which 20 wt% Cu. Results optimum excess copper content 20 wt%. Also, EIS an interaction between CuxO–TiO2 decisive in corrosion behavior samples.
