摘要	Titanium is not fully immune to the microbiologically-influenced corrosion, yet highly susceptible to biofouling. Biocorrosion inhibition effect of Ti-5Cu alloy against Pseudomonas aeruginosa was studied using antibacterial test, various electrochemical techniques and surface analysis. Ti-5Cu alloy was verified to effectively reduce the MIC rate. After 14 days of incubation in P. aeruginosa, the icorr of cp-Ti (89.20 +/- 12nA cm(-2)) was significantly greater than that of Ti-5Cu alloy (35.42 +/- 5.3nA cm(-2)). Release of Cu2+ ions which was confirmed by shake-up feature controlled respiration of P. aeruginosa, resulting in strong pitting resistance ability. The outermost layer of Ti-5Cu alloy was predominantly composed of TiO2, but a spot of Ti degrees was also detected. In contrast, the content of Ti2O3 at sputtering thickness of 0, 2, and 6 nm was higher on the surface of cp-Ti compared with Ti-5Cu alloy. Ti2Cu intermetallic compounds promoted the rapid self-healing property of passive film in the presence of P. aeruginosa.
