Study on surface hydrogenated Ti6Al4V alloy for orthopedic implants

Titanium-based alloys exhibit superior resistance to corrosion and biocompatibility in comparison to other alloys utilized for implant applications, such as stainless steel and cobalt-based alloys. Nonetheless, no completely inert metal is suitable for implantation in the human body, as aseptic loosening of the implant or the release of ions in the vicinity of the implant can result in inflammation and implant failure. Therefore, the primary objective of this study was to employ hydrogenated titanium 6-aluminum-4-vanadium (H–Ti6Al4V) alloy to reduce reactive oxygen species (ROS) and thereby achieve the function of regulating inflammatory signaling when employed as an implant.
