Paper No: WTC2005-64345
... In 1966 a report published by UK Department of Education and Science introduced the concept of tribology, which was defined as the science of interacting surfaces in relative motion. Tribology in practice studies friction, wear and lubrication. These processes affect each other with interacting...
