Metallic Biomaterials

In the area of metallic biomaterials we work strongly on degradable magnesium alloys for bioresorbable implants, which render an implant removal surgery unnecessary. In the past, we have pioneered the field with the development of rare-earth free magnesium alloys with outstanding mechanical and biomedical properties. These involve DownloadMgZnCa glasses (PDF, 1.1 MB); ultrahigh-purity Mg (WO/2021/165139A1); fine-grained lean DownloadMgZnCa alloys (PDF, 1.3 MB); and fine-grained microalloyed MgCa alloys (WO/2023/281054A1).

The rare-earth-free magnesium alloys have alloying contents of less than 1 at.% (lean Mg alloys) or 0.3 at.% (microalloyed Mg), respectively. We study their fundamental electrochemical, biological, and mechanical properties from the atomic to the macroscopic scale, and collaborate with veterinarians, cell biologists and clinicians to forward the field for human well-being.

In the area of lean and microalloyed Mg we focus on their:

We also focus on additive manufacturing and other processing methods of bioresorbable Mg alloys:
