Welcome to Tribology and Surface engineering Laboratory
Tribology is defined as the science and engineering of interacting surfaces of two bodies. It involves studies such as adhesion, friction, lubrication (solid or liquid) and wear. Example of such surface interactions in engineering are numerous which includes gears and cams in automotive machines, different types of bearings, tyre/road interactions, brakes, railway wheel/track interactions, engine/piston interactions etc. Even in nature, we have tribological designs in human joints such as hip and knee. More recent trend is to study tribology at nano-scale interactions such as those encountered in magnetic hard disk drives, micro-electro-mechanical systems, nano/micro-machining etc.
Tribological problems can be solved by applying various engineering solutions. Lubrication, coatings, hardening of surfaces, texturing are some of the solutions that can be engineered based on specific application, thermal/stress conditions and the environment.
In our laboratory, we strive to study adhesion, friction and wear in detail and provide scientific explanations to these phenomena. We can provide newly engineered tribological solutions to various surface related problems. Our areas of research include:
·       Nanotribology involving AFM, FFM and surface force apparatus
·       Polymer (base and composites) and soft matter tribology
·       Hard and soft coatings and surface modifications for low friction and wear durability

·       Nanolubrications of micro- and nano-scale machines
