Oil Lubrication
What is Lubrication? Lubrication is the process of reducing wear and friction by applying a film that reduces friction between two surfaces in contact. The lubricant employed could be a solid, fluid, or plastic material. […]
Tribology Wiki
Tribology Wikipedia has the same goal as the well-known Wikipedia: share knowledge from around the globe and create an encyclopedia accessible to anyone. Of course, Tribology Wiki has an emphasis in Tribology! Everyone is invited to read, write, edit and share Wikis.

Dry Lubricants
What are Dry Lubricants? Dry lubricants or solid lubricants are substances that, even though they’re within the solid phase, can decrease the friction of two materials that slide against one another without the requirement of […]
Introduction to Tribology
Definition of Tribology. Tribology is the science of friction, wear, and lubrication and is truly interdisciplinary. It studies the interaction of moving surfaces and every aspect related to friction, wear, lubrication, adhesion, tribo-chemistry, etc. Tribology solutions […]
Stern Tube Sealing System
Most ships are driven by the engine-shaft-propeller arrangement shown in Figure 1. The stern tube is a metal tube welded to the hull of the ship connecting the engine chamber and the outside of the […]
Elastomers
Glass Transition Temperature It is not clear what is the difference between an “elastomer” and a “rubber”. It is nowadays accepted to use them indistinctively and this is how it is treated in the following […]
Rheology – The Science Behind Material Flow
Rheology is the science of flow and deformation of a particular matter that describes the interrelation between force, deformation and time. It is the study of how materials respond to applied stress or strain. Rheology performs […]
Creep Deformation
Background The meaning of creep as per the English dictionary is as follows: creep is essentially an act of moving slowly and carefully in order to avoid being heard or noticed. Well, this is what […]
What is grease?
Grease Grease is a semisolid liquid that consists of a liquid lubricant mixed with a thickener. The oil does the lubricating while the thickener holds the oil and provides a resistance to flow. Soaps (a […]
Density of Oil
What is oil density? Oil density is a crucial property not only in lubricants but in all fluids. For instance, as the density of a lubricant increases, the fluid becomes thicker. This leads to an […]
Starvation
It is said that a contact operates under “starvation conditions” when an increase of oil supply at the contact would result in an increase of the film thickness at the contact. In other words, when […]
