Article Synopsis
- Researchers developed solid lubricant coatings using TiCT-Graphene Oxide blends, which were spray-coated on bearing steel surfaces to enhance performance in industrial applications.
- Testing revealed these coatings significantly reduced friction to 0.065 at high pressures while also protecting against wear better than traditional single-component coatings.
- The performance was linked to the creation of a robust tribolayer during operation, as shown through various advanced microscopy and spectroscopy techniques, emphasizing the connection between the material's structure, properties, and processing.
High-contact stresses generated at the sliding interfaces during their relative movement provide a unique combination of local heating and shear- and load-induced compression conditions. These conditions, when involving the sliding of surfaces with certain material characteristics, may facilitate tribochemical reactions with the environment, leading to the formation of a protective, damage-suppressing tribofilm directly at the contact. Here, we employ the electrodeposition process to design a coating composed of a hard cobalt-phosphorous matrix with the inclusion of tribocatalytically-active nickel clusters.

- Researchers are working towards achieving superlubricity, or nearly zero friction, by applying a blend of TiCT and MoS as a lubricant on rough steel surfaces.
- Tests revealed that these nanocomposites could create superlubricious states, which had not previously been observed in either material alone under similar conditions.
- Advanced techniques like Raman spectroscopy and electron microscopy helped identify a robust tribolayer that contributed to impressive lubrication performance at high pressure and sliding speeds.
