研究了热处理后的冷却速率对Ti6Al4V-5Cu合金显微组织、力学性能、耐蚀性能及抗菌性能的影响。将合金分别进行不同冷却方式的热处理,即在740 ℃三相区分别进行水淬、空冷和炉冷,在820 ℃两相区和910 ℃单相区分别进行水淬。结果表明,炉冷合金由于初生α相的尺寸和体积分数最大,所以塑性最好;合金在740和820 ℃分别水淬后,由于组织中存在正交α′′相,其硬度和屈服强度显著降低;合金在910 ℃水淬后由于存在针状的hcp α′相,其硬度和抗拉强度最高,但塑性最差。随着热处理温度的升高,合金中的元素分布逐渐均匀,其耐蚀性能随之提高。改变冷却速率并不明显影响合金的抗菌性能,不同冷却速率下的合金都具有优异的抗菌性能。

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 α phase in microstructure. The alloys water quenched from 740 and 820 ℃ respectively demonstrated low hardness and yield strength due to the existence of orthorhombic α′′ phase in microstructure. The alloy quenched at 910 ℃ showed the highest hardness and tensile strength, but the lowest plasticity because of the presence of acicular hcp α′ 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.
