According to our (Global Info Research) latest study, the global Plasma Electrolytic Oxidation (PEO) market size was valued at US$ 105 million in 2025 and is forecast to a readjusted size of US$ 155 million by 2032 with a CAGR of 5.8% during review period.
Plasma Electrolytic Oxidation (PEO), also known as Micro-Arc Oxidation (MAO), is an advanced surface treatment process used to improve the surface properties of various metals, particularly light metals like aluminum, magnesium, and titanium. PEO is a high-voltage, high-frequency, and low-current electrochemical surface treatment method that forms a hard, ceramic-like oxide layer on the metal's surface. This oxide layer enhances the metal's corrosion resistance, wear resistance, and other functional properties.
The core driving force of global plasma electrolytic oxidation comes from the rigid demand for lightweight and corrosion-resistant coatings in aerospace and high-end medical implants. The growth rate of the Chinese market leads the world; international giants Keronite and IBC Coatings monopolize high-end fields such as aircraft engines and gas turbine blades. Technological iteration focuses on composite processes (MAO+graphene/PTFE enhancement) and green electrolytes (chromium-free formula meets EU RoHS), but the high energy consumption of electrodes (accounting for 50% of the cost) restricts the increase in penetration. In the next five years, with the popularization of integrated die-casting car bodies and the acceleration of lightweighting of space equipment, the market will maintain growth, and intelligent production lines (AI real-time control of film thickness) and regional foundry clusters will become the key to competition.
