Surface modification of Zirconium based alloys for bio application by Micro-arc oxidation process: A Review

Abstract

Abstract Because of their superior mechanical properties, metal implants are the ideal choice for long-term reconstruction of hard tissues like the hip and knee joints. Zr and its alloys are widely recognized as biocompatible metal implants because of the self-regulating oxide coating that prevents the surface from corrosion and restricts ion release. The Osseo incorporation of these critical elements requires surface modification. The surface of metal implants is modified via micro-arc oxidation (MAO). The goal of this study is to give a summary of contemporary Micro-arc oxidation (MAO) research on zirconium and related alloys in biometal implants.
