Corrosion and mechanical behavior evaluation of in-situ synthesized Cu-TiB2 nanocomposite

In this paper, the synthesis of copper matrix nanocomposite and effect adding TiB2 nanoparticles on was investigated. Three different amounts 5, 10, 15 wt% were added sintering carried out at 900 oC for 4 hours under argon atmosphere. The phase formation achieved nanocomposites studied by X-ray diffractometer morphology synthesized samples field emission scanning electron microscopy atomic force microscopy. polarization electrochemical impedance spectroscopy (EIS) 3.5 NaCl solution room temperature to evaluate corrosion behavior samples. Results show that decrease resistance galvanic couples, but porosities is higher. It revealed variation surface roughness in direct relation value current density.
