Surface integrity modification of CoCrMo alloy by deep rolling in combination with sub-zero cooling as potential implant application.

Alloys made of CoCrMo are well established as implants materials since decades in orthopedic surgery. The good mechanical properties, biocompatibility and especially the corrosion resistance are important rationales for the use of these alloys. Nevertheless, retrieved implants from revision surgery showed the occurrence of abrasion and corrosion.
