Developing a new laser cladded FeCrMoCB metallic glass layer on nickel-free stainless-steel as a potential superior wear-resistant coating for joint replacement implants

Biomedical implants are made of biomaterials such as titanium, cobalt-based alloys or stainless-steel depending on which is the most suitable. However, metallic alloys have failed to prove high wear resistance alongside acceptable biocompatibility. Recently, metallic glasses (MG) have attracted more...
