Latest research on biomedical CoCrMo alloys

Excited to share our latest research on biomedical CoCrMo alloys and the potential of deep cryogenic treatment (DCT) to improve implant performance published in @Corrosion Science (Elsevier). 🦴 🩻 🥼

Cobalt-chromium-molybdenum (CoCrMo) alloys are widely used in orthopaedic joint replacement implants because of their excellent mechanical strength and biocompatibility. However, challenges such as corrosion, wear, long-term durability, and metal ion release still remain critical concerns in biomedical applications.

💡 In this study, we investigated the influence of deep cryogenic treatment at −196 °C on biomedical-grade wrought low carbon CoCrMo alloy, comparing conventional heat treatment with DCT durations of 24 and 48 hours. Using SEM, XRD, Raman spectroscopy, corrosion testing, micro-residual stress analysis, and microhardness evaluation, we observed promising improvements in:

✔️ Corrosion resistance

✔️ Surface micro-residual stresses

✔️ Microhardness

The findings highlight the potential of DCT as an effective post-processing approach for enhancing the performance and reliability of CoCrMo biomedical implants. ⬅️

A great step forward toward more durable and reliable orthopaedic materials. ⚠️

CryoFusion meets DLR

What a great day at German Aerospace Center (DLR) in Cologne at the Institute for Frontier Materials on Earth and in Space! I would like to thank Dr.-Ing, Ronja Anton for inviting me and hosting us today.

I had the opportunity to present on the SURFACES group projects, with a deeper dive into my CryoFusion project, which is funded by European Commission. I shared key results and discussed how DCT influences microstructure and residual stresses—and how these changes ultimately impact properties such as corrosion and wear resistance, as well as magnetic and mechanical performance of alloys used in energy sector.

I would also like to thank the team for the insightful tour of the institute, where we had the chance to explore a variety of impressive laboratories.

A special thanks as well for the fruitful discussions on potential future collaborations—looking forward to what lies ahead!

I would also like to thank co-director of Institute for Frontier Materials on Earth and in Space Prof. Guillermo Requena for taking the time to meet with us in person and for seeing our presentations.

Futhermore, I would like to thank also Prof. @Florian Kargl, Dr. Hubertus Thomas, Dr. @Mikhail Pustylnik, @Phillip Eckstein and all the others who hosted us from different departments.

Thank you to everyone for the engaging discussions and valuable feedback!

I would like to thank also Dr.-Ing. Matic Jovičević-Klug for presenting his projects and being involved in the discussions.
