[0023] Such as figure 1 Shown, present embodiment provides a kind of preparation method of Ti-3Cu antibacterial material, comprises the following steps:
[0024] S1: After mixing titanium powder and copper powder at a mass ratio of 97:3, ball mill for 3-6 hours to obtain a mixed powder.
[0025] It should be noted that due to the strong combination ability of titanium at high temperature, it can not only combine with oxygen, carbon, nitrogen and many other elements to form titanium compounds, but also the melting temperature of titanium compounds is not consistent with the vacuum melting temperature. However, the titanium compound and the smelting mixture are smelted in the same state, and the vacuum smelting time is mainly based on meeting the smelting settings of pure titanium and pure copper, resulting in insufficient smelting of the titanium compound and segregation. Therefore, in the embodiments of the present invention, both the copper powder and the titanium powder are...
Embodiment 1
[0037] Present embodiment 1 provides a kind of preparation method of Ti-3Cu antibacterial material, comprises the following steps:
[0038] S1: After mixing titanium powder and copper powder at a mass ratio of 97:3, ball mill for 4 hours to obtain a mixed powder;
[0039] S2: Under the condition of 670℃, vacuum sinter the mixed powder for 1.2h, and the vacuum degree is 1×10 -3 Pa;
[0040] S3: Continue sintering for 1.0 h under the protection of argon and a temperature of 850 °C, and then introduce ultrasonic waves into the sintered melt under the protection of hydrogen and argon and a temperature of 850 °C for 3 min, in which The power is 600W;
[0041] S4: Cool the ultrasonically treated sintered melt to 720°C, pressurize and keep it warm for 2.5h, then cool it down to 420°C, keep it warm for 8h, and the pressurized strength is 22MPa;
[0042] S5: After the heat preservation is completed, the water is cooled to room temperature and cut to obtain the Ti-3Cu antibacterial m...
Embodiment 2
[0044] Present embodiment 2 provides a kind of preparation method of Ti-3Cu antibacterial material, comprises the following steps:
[0045] S1: After mixing titanium powder and copper powder at a mass ratio of 97:3, ball mill for 4 hours to obtain a mixed powder;
[0046] S2: Vacuum sintering the mixed powder for 1 hour at a temperature of 700°C, where the degree of vacuum is 1×10 - 4 Pa;
[0047] S3: Continue sintering for 0.5h under the protection of argon and a temperature of 950°C, and then introduce ultrasonic waves into the sintered melt under the protection of hydrogen and argon and a temperature of 950°C for 5 minutes. The power is 400W;
[0048] S4: Cool the ultrasonically treated sintered melt to 750°C, pressurize and keep warm for 2h, then cool down to 450°C, keep warm for 5h;
[0049] S5: After the heat preservation is completed, the water is cooled to room temperature and cut to obtain the Ti-3Cu antibacterial material.
