Replicating the complex surface topographies of nature Approximately more than 400 million years of land plants evolution led to a vast diversity of structures on plant surfaces [1]. The surfaces of plant leaves are rarely […]
Boundary Lubrication Boundary lubrication is the lubrication regime where the interface behaviour is dominated by chemical reactions that happen at the surfaces, tribofilm formation occurs, and the load is carried by the asperities. In the boundary lubrication regime the […]
Since the early 1970s, the usage of Environmentally Acceptable Lubricants (EALs) in the industry started to grow and different sectors started investing in the development of EALs, e.g. development of EAL hydraulic fluids for forestry […]
What is plastic deformation? Plastic deformation, in general, can be defined as a permanent deformation, a non-reversible change in the geometry of a body under applied stresses (forces). For example, if hit sufficiently hard by […]
What is Boundary Lubrication? Boundary lubrication describes situations where the applied load is primarily supported by contacting solid asperities, rather than a liquid lubricant. The boundary lubrication regime acts when the lambda ratio (the ratio […]
Primary purpose of any industrial lubricant is to maintain a satisfactory lubricating film in between contacting surfaces; and importance of viscosity to achieve this is univocally known in industrial maintenance practices. However, what is often […]
Temperature – Viscosity Relation Viscosity is a measure of a lubricating oil’s resistant to flow. It is well-known from Hydrodynamic Lubrication Theory that viscosity plays a central role in the lubrication regime encountered in the […]
The Engine Bearing (Main Bearing) The internal combustion engine (piston engine) currently is still the most common engine used in automotive indutstry, even though the electric vehicles using electric vehicles are getting rapidly popular. Combustion […]
Amonton’s laws of friction are categorized as the classical version of friction laws which have highly been accepted by the engineers dealing with friction. Guillaume Amontons has earned his name in the field of physics […]
