摘要	The Cu-containing titanium alloy has been proved to possess excellent antibacterial performance, which has great potential for clinical application. In this work, the effect of cooling rate on the microstructure, mechanical properties, corrosion resistance and antibacterial property of a Ti6Al4V-5Cu alloy was investigated. Results showed that the furnace-cooled alloy exhibited the best ductility because of the maximum size and volume fraction of the primary a phase in microstructure. The alloys water quenched from 740 and 820. respectively demonstrated low hardness and yield strength due to the existence of orthorhombic alpha'' phase in microstructure. The alloy quenched at 910 degrees C. showed the highest hardness and tensile strength, but the lowest plasticity because of the presence of acicular hcp alpha' phase. With the increase of heating temperature, the elemental distribution in the alloy became more uniform, and therefore the corrosion resistance increased gradually. However, the cooling rate did not obviously change the antibacterial property of the alloy. The Ti6Al4V-5Cu alloy showed excellent antibacterial property under different cooling rates.
