Abstract (EN): Corrosion behavior of joined Ti-B4C composites was evaluated in 9 g/L NaCl solution using cyclic polarization and electrochemical impedance spectroscopy. Tribocorrosion behavior was investigated by sliding against an alumina ball under open-circuit potential and potentiodynamic polarization. The results showed that joining did not negatively affect the corrosion behavior of the composites. Regarding tribocorrosion, while joining did not significantly influence the coefficient of friction and total wear volume loss, it resulted in slightly increased electrochemical activity under sliding. These results showed that brazing may be considered as a simple and low-cost technique for joining Ti-B4C composites to be operated in tribocorrosive environments.
