Micro- and nano-scale tribo-corrosion of cast CoCrMo

Significance of output:

First paper to fully explore the micro-/nano-scale CoCrMo tribocorrosion behaviour for metal-on-metal hip replacements. Such data is vitally important to allow better understanding the medical concerns related to the use of these implants, especially in terms of biocompatibility associated with repassivation kinetics of mechanically induced corrosion. We developed a mathematical model to study the CoCrMo repassivation kinetics after surface oxide film rupture critically allowing greater insights into the nature of the CoCrMo micro-/nano-scale wear-corrosion mechanisms and deformation processes – directly linked to the August 2010 DePuy recall. This work has consolidated nCATS collaborations with Southampton General Hospital, Spire Hospital and DePuy.
