1. Steel has a wide range of applications yet is prone to corrosion in various media. Massive quantities of steel worldwide are lost to corrosion every year. Protective coatings can not only extend the service life of components but also endow materials with special engineering properties.
2. Corrosion causes direct material loss, indirect economic losses from production shutdowns, and even risks to personal safety and property. New high-strength materials used in aerospace and other sectors feature sophisticated structures that are more susceptible to corrosion, calling for brand-new supporting protection technologies.
3. Metal corrosion has attracted extensive attention, driving the continuous advancement of anti-corrosion technologies. Anti-corrosion measures mainly fall into two categories: environment regulation and metal matrix modification, which are further divided into five specific approaches: adjusting corrosive environments, developing corrosion-resistant materials, applying protective coatings, electrochemical protection, and optimizing material selection and structural design.
4. Among all anti-corrosion methods, coating protection boasts the broadest application scope with a great variety of construction techniques and coating materials available.
