| 摘要 | The antibacterial performance of a Cu-bearing CoCrMo alloy was studied by use of antibacterial function of copper (Cu) ions. Results show that the Cu-bearing CoCrMo alloy has broad-spectrum antibacterial features, and the antibacterial rates against both E. coli and S. aureus selected in the present work all reach above 95.7%. Through studies of different concentration of E. coli on antibacterial rate of Cu-bearing CoCrMo alloy, it is proved that the alloy has good antibacterial performance against E. coli below 1 x10(6) cfu/ml, and with increase of the concentration of E. coli, the antibacterial performance drops quickly. The bacterial biofilm observation indicates that Cu-bearing CoCrMo alloy could effectively reduce the number of bacteria on the surface, and then inhibit the formation of the biofilm. The electrochemical experiment reveals that after contacting with E. coli, the release of Cu irons from Cu-bearing CoCrMo alloy becomes faster, resulting in certain decreases of the self corrosion potential and pitting potential of the alloy. |
