| Abstract Scope |
This talk presents recent results on toxic-element free biocompatible Ti-based metallic glasses, providing long-term safety in the human body. Since such alloys have inherently rather low glass-forming ability (GFA), they suffer limitations concerning sample size and geometry upon quenching, limiting their practical applications. However, they can be shaped and patterned through thermoplastic forming (TPF) in the supercooled liquid region. This enhances their practicality and functionality through TPF approaches.
We first focus on alloy development of truly biocompatible compositions with optimized GFA and corrosion properties / ion release characteristics. The second focus targets the feasibility of TPF shaping and patterning for selected compositions, allowing to create hierarchical macro- to nano-scale surface patterns. The third focus demonstrates the versatility of different surface topographies for possible orthopedic tissue implants or dental implants. The final focus combines the designability and versatility of thermoplastic forming beyond biomedical applications, presenting first results for catalytic applications. |
