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. ⚠️
