About this Research Topic
Friction, wear, and corrosion play a crucial role in several fields, including biomanufacturing, optics, materials science and medicine, and their implications are far-reaching and complex. Among them, friction consumes 30% of the world's disposable energy, and about 80% of machine parts fail due to abrasion. At the same time, the annual economic loss attributed to corrosion represents about 5% of GDP. Friction, wear, and corrosion result in significant energy consumption and economic losses for nations and societies. Reducing energy dissipation, improving interface lubrication performance, and enhancing corrosion resistance have become widely discussed issues. Two-dimensional semiconducting materials are widely used in the above fields for friction reduction and consumption reduction due to their excellent properties, such as transition metal dichalcogenide for biosensors, graphene for photodetectors, boron nitride for lubricating coatings, and chalcogenide for supercapacitor. However, numerous influencing factors at friction interfaces and material surfaces are prone to defects, presenting challenges to achieve ultra-low friction and wear, and high corrosion resistance in practical engineering applications.
Two-dimensional semiconducting materials with excellent lubrication, optical, and electrical properties have been extensively studied in recent years and can be used to reduce friction, wear, and corrosion in a variety of fields. However, they still face many challenges in practical applications, including unclear mechanisms of friction energy dissipation, inaccurate detection of micro-interaction processes at material interfaces, and inefficient surface protection and control of ultra-low friction and wear. Therefore, it is important to further investigate the mechanisms of surface and interface friction and wear, develop high-precision detection technologies for micro-processes, and propose efficient surface-strengthening methods. Addressing the above challenges in different fields such as bio-manufacturing, optics, materials science and medicine, molecular dynamics simulation, experimental data, theoretical analyses, and other methods can be used to show the improvement effect of the method on friction, wear, and corrosion performance.
The scope of the Research Topic includes but are not limited to:
• Microscopic mechanism of friction energy dissipation;
• New method for detecting microscopic defects on the surface of two-dimensional semiconducting materials;
• Corrosion and protection technology for two-dimensional semiconducting materials;
• Preparation and performance study of lubricating coatings;
• Novel principles, methods, and ideas for friction/wear/corrosion.
