Real Contact Area
Introduction: In the entire world there are no smooth surfaces ideally. Asperities, shape, and height variations all allow us to identify surfaces. Depending on the scale used, even surfaces that appear to be well polished […]
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. Please contact us via email if you would like to contribute an article or if you have any suggestions! You can create an article by going to Create New tab in any of the existing articles (you must be logged-in)
Surface Coating Techniques
Introduction: Metal surfaces, particularly those of steels, require unique surface treatments to achieve the appropriate properties. Although there are several surface treatment procedures, surface coating techniques are the most popular. Coatings can provide a wide variety of qualities, […]
Surface Roughness
Definition Surface roughness is defined as the irregularities which are inherent in the production process (e.g., cutting tool or abrasive grit). It may be the result of vibrations, chatter, or work deflections and strains in […]
Tribological Surfaces
Introduction The surfaces that undergo friction wear and are lubricated in the mechanical components are called tribological surfaces. These surfaces have different surface topography depending on the type of applications. Most commonly tribological surfaces are […]
Elastohydrodynamic Lubrication Regime
Introduction The lubrication regime that occurs due to the elastic deformation of the lubricated contacts is the elastohydrodynamic lubrication regime. This lubrication regime is important for all lubrication regimes to understand because of its application […]
Boundary Lubrication Regime
Introduction The lubrication in any regimes at the contact interface of any mechanical components is very important because they are capable of controlling the tribological properties such as friction and wear of the interacting surfaces. […]
Hydrodynamic Lubrication Regime
Hydrodynamic Lubrication: Lubrication in any system at a sliding interface can be classified based on the amount of lubricant present at the interface. According to the stribeck curve (the plot of coefficient of friction (COF) […]
Fretting Wear
Definition: Fretting wear is a type of wear that is caused due to many cycles of the short amplitude reciprocating sliding movement at the interface of the material. The fretting wear causes severe damage causing […]
Mixed Lubrication Regime
Background: The lubrication regimes at the contact interface in any mechanical components are very important to be studied because it determines the efficiency of the components. The type of regime determines the tribological properties of […]
Low Oil Pressure
The lubricating oil inside the engine will ensure that all moving parts inside the engine are properly lubricated and safe. When the oil flows through the open spaces within your engine, pressure builds up. This […]
