Wettability
Introduction Wetting is a very important property to understand the bonding and adherence strength of a solid surface or any two materials. The adhesive forces in the liquid help in spreading across a solid surface […]
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.

Infrared spectroscopy
Introduction Infrared (IR) spectroscopy deals with the infrared region of the electromagnetic spectrum, i.e., light having a longer wavelength and a lower frequency than visible light. Infrared light was discovered in the 19th century which […]
Scanning Electron Microscope
Introduction The optical microscopes that use light as the main source to observe any material surface are limited by their resolution in comparison to the electron microscopes. Scanning electron microscopes (SEM) have been commercialized for […]
Greenwood Williamson Model
Introduction Real contact area It is usually assumed that the real area of contact between two nominally flat metal surfaces is determined by the plastic deformation of their highest asperities. This leads to the result […]
Stylus profilometer
Introduction Analyzing the material’s surface characteristics with precision is very important for mechanical component parts and there are various techniques that are sophisticated and precise. There are various 2D and 3D surface profilometers and optical […]
Optical Profilometer
Introduction Profilometry is a technique that is used to obtain topographical data from surfaces. The data drawn can be either single point, line scan, or three-dimensional data. The topographical characteristics of the surface such as […]
Atomic force microscopy
Introduction The microscopic technology which is used to observe and measure the surface topography of the materials with greater resolution and accuracy is Atomic force microscopy (AFM). The major limitations of the Scanning tunneling microscope […]
Temperature in Tribological Contacts
Introduction In tribology, the flash temperature is the sharp temperature rise that takes place at the interface between two rubbing solids upon motion. Solid surfaces, irrespective of their method of formation, contain irregularities or deviations […]
Oil Sampling Ports
Introduction: A powerful method for inspection of oil wetted machine parts is wear particle analysis. Wear Particle analysis (WPA) is very important to identify the wear mechanisms [1].Complex machines and their parts (which are huge) in an industry […]
Surface Energy
Introduction Adhesion is the tendency of dissimilar surfaces to stick to one another. It can be measured in terms of work of adhesion in J/m2. It is the energy needed to separate 1m² of joined […]
