Recent progress on surface texturing and solid lubricants in tribology: Designs, properties, and mechanisms

This study provides a review of recent progress on designs, properties, and mechanisms of surface texturing and solid lubricants. Firstly, the design and processing of surface texture, the type of solid lubricants and the preparation method of texture combined with lubricants are mentioned in design strategy, respectively. Then, effects of surface texture and solid lubricants on tribological properties are analyzed, including antifriction, wear-resistance and other beneficial effects. Next, the synergistic effect mechanisms of surface texture and solid lubricants are discussed, focusing on the effect of texture on the surface/interface of lubricating coating and the lubrication effect of solid lubricants by texturing. Finally, this review looks forward to the problems and future development of texture and lubricants.
