Tohoku University Technology: CuO-added Biocompatible Ti Alloy: T24-104
Both mechanical properties and antibacterial properties are improved. Can be produced with a 3D printer.
Titanium (Ti) alloys are widely used in the medical field due to their lightweight, non-magnetic, corrosion-resistant, and biocompatible properties. However, Ti has low antibacterial properties, making it prone to bacterial infections when used in dental implants, and it also has low resistance to inflammation, leading to rapid progression once an infection occurs. Additionally, there are concerns about limited durability due to insufficient strength, and the manufacturing of dental implants, for example, requires multi-stage processing, which is costly. This invention confirms that samples made from Ti-CuO composite powder through additive manufacturing exhibit excellent mechanical properties and antibacterial characteristics. The improvement in mechanical properties is attributed to the solid solution strengthening element O, while the enhancement of antibacterial properties is believed to result from the rapid cooling and solidification by laser during additive manufacturing, which prevents the formation of coarse Ti-Cu intermetallic compounds due to the supersaturation of Cu.
