All conventional lubricants borne of classic hydrodynamic theory are designed to provide lubricity. Inherent in the desire to provide lubricity to mechanical systems is the desire to protect the interacting metal surfaces from wear. Much […]
2D materials are single or only few atomic layer thick and posses unique properties with potential in many technological fields. They are highly anisotropic, having significantly different properties in-plane and perpendicular-to-the-plane. For example, graphene, […]
The first challenge when measuring a surface topography via optical techniques is getting the sample to the lab. Although optical surface roughness measurement does not damage the component per se (NDT), the fact of fitting […]
Atomic Force Microscopy (AFM) is a powerful and convenient experimental measurement device in the field of nano-scale tribology. It was successfully applied to explore superlubricity in a graphene-gold interface and superlubricity due to repulsive van […]
Superlubricity, a state of low friction (<0.001), can be achieved by different mechanisms. The structural superlubricity occurs, if the crystal lattices of the contacting bodies are incommensurate. Nano-scrolls may act as a bearing and may […]
In order to improve wear resistance of the surfaces operating in harsh conditions, along with base oils additives are frequently used. ZDDP is one of the best additives in terms of antiwear performance, however, environmentally […]
