This book is a comprehensive collection of research papers presented at 22nd International Corrosion Congress held on October 22–26, 2024, in Xi'an, China. The book serves as a valuable resource of the critical progress and technical advances in corrosion and protection for academics, researchers, and professionals worldwide. The book focuses on the latest findings and progress of corrosion and protection in harsh environments including corrosion and protection of oil & gas and new energy materials, nuclear corrosion, high-temperature resistant materials and coatings, tribocorrosion, and cathodic protection.The International Corrosion Council (ICC), founded in 1961, consists of representatives of countries interested in increasing the benefits to be derived from the advancement of corrosion science and engineering. These representatives, currently from 64 member countries, are generally appointed by nationally recognized corrosion societies or by national organizations with a significant interest in corrosion. This committee acts for the Council between International Corrosion Congress meetings which are normally held every three years.
