AI Technical Summary
In the current high-copper-content titanium alloys, copper exists in the form of intermetallic compounds during the preparation process, which cannot effectively release copper ions, resulting in insignificant antibacterial effects and high costs, thus limiting their application in non-implantable medical devices and daily life.
Using inexpensive titanium alloy coarse powder, 3D printed titanium alloy recycled powder, and electrolytic copper powder as raw materials, copper-containing titanium alloy plates are prepared through powder metallurgy and process control. This ensures the presence of Ti2Cu phase, solid solution copper, and elemental copper in the alloy. The particle size difference of the powder fills the voids to form a heterogeneous structure. The release of copper and the plasticity of the alloy are controlled by combining hot isostatic pressing, hot rolling, and cold rolling processes.
It achieves low-cost and high-efficiency antibacterial effect, with rapid release of copper ions, short sterilization time, high alloy strength and good plasticity, expanding its application range to non-implantable medical devices and daily life.
