Corrosion Behavior of SHS-Produced Cu–Ti–B Composites

Corrosion Behavior of SHS-Produced Cu–Ti–B Composites

Metal-matrix Cu–Ti–B nanocomposites were prepared by SHS method and their corrosion behavior was characterized by XRD, atomic force microscopy, polarization testing, and electrochemical impedance spectroscopy. Microhardness of synthesized composites attained a value of up to 544 H V . The presence o...

Beschreibung
Zusammenfassung:Metal-matrix Cu–Ti–B nanocomposites were prepared by SHS method and their corrosion behavior was characterized by XRD, atomic force microscopy, polarization testing, and electrochemical impedance spectroscopy. Microhardness of synthesized composites attained a value of up to 544 H V . The presence of BN, Cu 3 Ti, and TiO phases leads to formation of Cu/BN, Cu/Cu 3 Ti, and Cu/TiO galvanic pairs which accelerate corrosion.
