Review: The Surface Modification of Pure Titanium by Micro-Arc Oxidation (MAO) Process

Titanium and titanium alloys are broadly used in biomedical applications, particularty orthopaedic and dental implants, due to their suitable properties, such as low modulus, high specific strength to weight, high machining, high corrosion resistance, and biocompatibility. Micro-arc oxidation (MAO) is one in every of many surface modification processes that can provide porous, adhesive, and bioactivity for implantation, resulting in better and more improved osseointegration. Furthermore, antimicrobial surface coatings hold a lot of promise for reducing infection-related errors. This study provides a summary of the biological evaluation of bioactive coatings. It primarily focuses on ways for enhancing the biological characteristics of MAO-coated titanium and related alloys. The overview is to discuss the MAO process of the titanium implant to enhance bone/implant interaction.
