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 […]
Oil lubrication and lubrication technologies are essential in reducing friction and wear losses in machines. The key in efficiency of the frictional system is a lubricant (grease, oil, solid lubricants). Four Ball Tester, also known […]
Pin on Disk Test Friction and wear (typically wear rates and wear resistance) characterization of materials is typically performed using various types of tribometers, while pin on disk test being probably one of the most […]
What is Nanotribology? Nanotribology or molecular tribology is one of the most significant components of tribology which is concerned with atomic and molecular interaction at a nanoscale, occurring upon the frictional contact of materials or lubrication. […]
What is Triboluminescence? Triboluminescence is tribology phenomenon resulting in the generation of light through creating any frictional interaction between the materials. The term for this phenomenon comes from a combination of the greek word for […]
What is triboelectricity? Triboelectricity refers to the electrification of dissimilar objects or materials occurred due to the collision resulting in the phenomenal flow of electrons from one material to other balancing the potential difference. The […]
What is fretting? Fretting or fretting wear is a specific wear type which is characterized by low amplitude oscillating sliding between bodies, which are nominally at rest [1] (for example due to vibration, cyclic stresses, […]
