Wear of materials
Introduction The materials undergo wear due to various reasons, the mechanical action exerted on its surface, the environmental factors, the physical and chemical nature, due to the process like fatigue and creep, etc. It is […]
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.

Friction of Materials
Introduction The friction of materials is an important property to be studied to understand its role in any mechanical applications. The tribological properties of any material are determined by its frictional behaviour, this behaviour will […]
Contact angle measurements
Introduction Wettability is a surface property of any material which is important to be studied to understand its affinity towards any liquid medium. Contact angle measurements are the way to understand wettability of the surface. […]
Adhesion: Definition, Theory and Types
Introduction Adhesion is one of the important material behavior to be considered to understand the influence of the interactions between the different materials in nature. This knowledge is also applied in case of the man-made […]
Coefficient of Friction derivation in Reciprocating Contacts
Reciprocating contacts are common in many engineering applications, e.g., hydraulic/pneumatic cylinders, crank-slider mechanisms (piston rings-cylinder), fretting vibrations, cyclic stresses, etc. The coefficient of friction in a reciprocating contact is usually detrimental when designing the component […]
Fourier Transform Infrared Spectroscopy
Introduction The main goal of the spectroscopy techniques is to measure how much light is absorbed in each wavelength shined on any material. This is easily done by using the dispersive spectroscopic technique by shining […]
Transmission electron microscopy
Introduction The microscopic techniques for analyzing and characterizing materials have been developed and researched over the decades. The specifications of the microscopes such as the magnification and resolutions vary from one microscope to another which […]
Raman spectroscopy
Introduction The interaction of light on materials is very different it may be transmitted, reflected, or scattered; the wavelength of the light affects the interaction with materials in different colors. This study of light is […]
XRD – X-ray diffraction
Introduction Materials characterization ion is one of the important aspects of the material science field and there are various techniques for analyzing and identifying the material and its composition. One of the techniques which use […]
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 […]
