Abstract
Tribology is derived from a Greek word which means to rub. It plays a vital role in various technical fields and optimizes polishing process. It improves and increases the lifespan of machines and other mechanical components. It also reduces the loss of power. Nanotribology is defined as the investigations of interfacial processes, on scales ranging in the molecular and atomic scale, occurring during adhesion, friction, scratching, wear, nanoindentation and thin-film lubrication at sliding surfaces. Nanotribological studies are thus needed to investigate the tribological phenomenon at a nanoscale as well as to look for nanotribological solutions. Another major development, which has become possible via nanotribology is the design of new smart materials and their fabrication. It is the branch of tribology that studies friction, wear, adhesion and lubrication phenomena at the nanoscale, where atomic interactions and quantum effects are not negligible. This paper mainly focuses on the concept of nanotechnology along with its history and various instruments like surface force apparatus, scanning probe microscope, atomic force microscope, scanning tunneling microscope and near field optical microscopy. Also it studies the measurement techniques, detecting the three dimensional indents and effect of all the methods with their applications.
