This review, authored by Robert J. K. Wood and Ping Lu, covers nearly 195 papers published in the past 15 years, highlighting the growing research interest in tribocorrosion coatings and surface modifications. The review emphasizes the need for machines to operate in harsh environments, leading to increased demands for longer service life, lower operating costs, and improved safety. The research has also focused on multifunctional coating surfaces and functionally graded systems. The review discusses various coating types, including molten-, solution-, PVD-, and PEO-based coatings, with CVD coatings being less popular. It highlights the importance of duplex surface engineering and coating systems, as well as the complex interactions between wear, friction, and corrosion rates. The review also addresses the influence of environmental factors such as pH, DO2, CO2, salinity, and temperature on tribocorrosion performance. Additionally, it covers a range of coating and surface modification solutions, including electrodeposited coatings, hard and tough coatings, and high-impedance coatings like doped diamond-like carbon. The review emphasizes the importance of microstructure, active phases, and surface films in tribocorrosion performance. It also discusses the challenges in modeling tribocorrosion, particularly the lack of understanding of synergistic and antagonistic mechanisms between wear and corrosion processes. Finally, the review provides an overview of the environmental effects on tribocorrosion, including the impact of pH, temperature, and other environmental conditions on material degradation.This review, authored by Robert J.
