[Display omitted] • The Ti 2 Cu of corrosion activity is composed of a "micro-galvanic cell" with α-Ti. • The lamellar Ti 2 Cu increased the Cu ion release caused by more galvanic interface. • The antibacterial rate of L-Ti 2 Cu is 99.5 %, due to the rapid release of Cu ions. The influence of morphology of the Ti 2 Cu phase on biological corrosion and antibacterial properties of Ti-Cu alloy was investigated by micro-galvanic corrosion. Elongated "micro-galvanic cells" were formed between lamellar Ti 2 Cu phase (L-Ti 2 Cu) and α-Ti matrix due to the different Volta potentials. The corrosion rate (V corr) of L-Ti 2 Cu was twice that of granular Ti 2 Cu phase (G-Ti 2 Cu) because lamellar Ti 2 Cu phase had more galvanic interface. The release of Cu2+ ions in L-Ti 2 Cu was 55 % higher than G-Ti 2 Cu, reaching 99.5 % of the antibacterial rate in L-Ti 2 Cu and providing a great potential in clinical application for dental implants.
