In-situ catalysis of green lubricants into graphitic carbon by iron single atoms to reduce friction and wear [PDF]
Reducing friction and wear in moving mechanical systems is essential for their intended functionality. This is currently accomplished by using a large variety of anti-friction and anti-wear additives, that usually contain sulfur and phosphorous both of ...

Synthesis of ultrathin two-dimensional metal-organic framework nanosheets for lubricant additives
Two-dimension (2D) nano materials are diffusely employed as lubricant additives. In this paper, three kinds of ultrathin 2D metal-organic framework (MOF) nanosheets with different metal ions (Ni2+, Zn2+, and Cu2+) were successfully synthesized by ...

ZDDP Tribofilm Formation on Non-Ferrous Surfaces
The current trend for using lower viscosity lubricants with the aim of improving fuel economy of mechanical systems means that machine components are required to operate for longer periods in thin oil film, boundary and mixed lubrication conditions ...

Scuffing failure analysis based on a multiphysics coupling model and experimental verification
General reductions in lubricant viscosities and increasing loads in machine components highlight the role of tribofilms in providing surface protection against scuffing. However, the relationship between the scuffing process and the growth and removal of
