Abstract
Abstract. Micro arc oxidation (MAO) is a surface treatment technique that involves forming a ceramic layer by processing metal surfaces under high voltage in an electrolytic environment. This method is widely used to strengthen and protect the surfaces of light metals, especially aluminum and its alloys. The effects of MAO on metal materials include changes in the mechanical, chemical and optical properties of the formed ceramic layer. Additionally, industrial applications and future potential of MAO are also discussed. The micro arc oxidation process creates a very thin and hard ceramic layer on metal surfaces. This ceramic layer increases the material's resistance to corrosion, wear and high temperatures. Additionally, the ceramic layer allows the surface to become smooth and coatable. As a result of the MAO process, the microstructure and composition on the material surface can change, allowing customized surface properties to be obtained according to different application requirements. Micro arc oxidation has broad application potential in many industrial sectors. It is widely used to strengthen and protect the surfaces of metal parts used in areas such as automotive, aerospace, defense, energy and medical devices. For example, in the automotive industry, the MAO process is used to strengthen the surfaces of vehicle body parts, engine components and other parts. In the aviation industry, MAO process is applied to increase the resistance of aircraft engine parts to high temperature and wear conditions. Micro arc oxidation process is an important surface treatment technique for strengthening and protecting the surfaces of metal materials. This method, which has a wide application potential, is widely used in industrial applications to meet surface protection and reinforcement requirements. In the future, it is expected that MAO technology will be further developed and its application areas will be expanded.
