Fatigue Wear: Proven Principles Governing Cyclic Stress and Wear Behavior 2026
Definition of Fatigue Wear: Fatigue wear is a type of wear in which the surface damage of the material takes place due to strain-induced on the surface for a particular number of cycles to a certain critical limit. The fatigue...
Hydraulic Fluids: Critical Insights for Optimal Thermal, Wear, and Viscosity Performance 2026
Hydraulic fluids are used for power transmission in hydraulic machinery. Hydraulic machines use fluid's ability to perform work. So, here is some example of equipment where usually hydraulic fluids are used like excavators and backhoe Loaders, hydraulic brakes, power steering systems,...
Tribometers: Critical Instruments Every Materials Engineer Must Know 2026
Introduction to Tribometers Tribometers are the devices used to analyse and characterise tribological systems. The most common direct measurement is the measurement of friction coefficient (and shear strength). During the post processing stage, other quantities can be measured, such as...
Abrasive Wear: Critical Insights Into Severe Material Loss & Prevention 2026
Definition: Abrasive wear is the type of wear mechanism that results in the disintegration of the material on the surface due to the influence of the hard particle in contact with the surface. It also occurs when a hard...
Hydrodynamic Lubrication: How It Ensures High Performance and Reliability 2025
Definition of Hydrodynamic Lubrication (HL) Hydrodynamic lubrication is a term that defines a situation in which two rubbing surfaces are separated by a thin film of a lubricant. This situation is often beneficial and lubrication is used to reduce friction...
Elastohydrodynamic Lubrication: Theory, Types & Practical Guide
What is Elastohydrodynamic Lubrication (EHL)? Elastohydrodynamic lubrication (EHL) describes a lubrication regime where high pressure causes significant elastic deformation of the contacting surfaces, deeply affecting the shape and thickness of the lubricating film. EHL is essential in many machine elements...
Surface Fatigue
Surface Fatigue describes surface fatigue as a practical tribology topic: how surfaces interact, how friction, wear, lubrication, material response, and operating environment influence performance, and what engineers should check when applying the concept in real machines or laboratory tests. Core...
Grease Lubricant: Essential Mechanisms and Selection Guide
TL;DR: A grease lubricant is a semi-solid lubricant made from base oil, thickener and additives. In tribology, grease is used when a machine needs long-lasting lubrication, sealing, corrosion protection and low leakage in bearings, gears, joints and sliding contacts. Key...
Coefficient of Friction: Critical Factors Influencing Tribological Performance 2026
What is a Coefficient of Friction? Friction is a force resisting relative motion and may occur at the interface between the bodies, but may also occur within the bodies. The concept of friction coefficient was first formulated by Leonardo da...
Rolling Contact Fatigue
Rolling contact fatigue (RCF) is a fatigue failure mechanism in rolling contacts where repeated Hertzian stresses create cracks near or below the surface. As cracks grow, material can detach as pits, spalls or flakes. RCF is a critical life-limiting process...
