ZDDP Tribofilm: Durability and Chemistry

01.03.2017 Aydar Akchurin 1495 Views
The classical lubrication theory suggests the use of oil to reduce wear by the development of a thin separating lubricating film. However, the trends in the industry dictate miniaturization of the mechanical devices with a […]

Controlling friction of graphene

02.02.2017 Aydar Akchurin 1022 Views
Graphene, a wonder just one atom thick material, shows incredible wear-resistance and super low friction levels. This behavior is ascribed to its low inter-layer shear properties and high normal load carrying capabilities. However, in many […]

Superlubricity with Green Lubricant

12.09.2016 Aydar Akchurin 1328 Views
Superlubricity is a state of vanishing sliding friction. It has been reported in glycerol/water mixture lubricated contacts, graphene-gold interface,  interface in presence of graphene and in other conditions. Increasing number of reports on superlubricity in […]

Slip, No Slip and Cavitation

05.09.2016 Aydar Akchurin 1620 Views
Engineering surfaces are heterogeneous and can be slippery or sticky locally depending on surface roughness and chemistry. The variation of surface properties affects the interaction between the wall and lubricant and determines friction. Slip can […]

Switchable Friction on Graphene

15.08.2016 Aydar Akchurin 658 Views
Graphene is a unique material in many aspects and has recently been applied in various ways. In tribology, it has been shown to lead to a superlubricity – an ultra low friction state. In laboratory […]
