Study of electrochemical proprieties of bio-inspired coating based ErGO

Abstract

It is stimated that 75% of failures in the articular prosthesis is due to bone resorption, caused by osteolysis due to the presence of wear particles that occur in the daily wear process of the components of the implanted joint. particles, traces and/or ions are accumulated in the surrounding tissues, interacting with cells and even incorporating into the bloodstream. Recent research has revealed the efficacy of sp3-sp2 hybridization carbón structures to reduce wear rate in metallic articular implants. Based on this, films composed of Electrochemically Reduced Graphene Oxide (ErGO) and ErGO functionalized with Hyaluronic Acid (ErGO-HA), which is the main component of the sinovial fluid, will be synthesized on the substrates CoCrMo and Ti6Al4V. The optimum conditions of synthesis, composition, morphology, roughness and, electrochemical and tribological performance, in addition, invitro biocompatibility tests will be performed under electrochemical control.
