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 […]

What is surface fatigue? Surface fatigue is the failure on the top layer of a body due to repeated loading. It can be differentiated from other types as it only occurs on the surface. It […]

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 […]

What is galling? Severe types of adhesive wear are often called galling, scuffing, welding or smearing, although these terms are sometimes used loosely to describe other types of wear. In metal-to-metal wear tests, high stresses […]

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 […]
