Tribology is the science of friction, wear and lubrication. The aim of this course is to deliver fundamental theory and concepts of tribology in a series of lectures, including lubrication theory, the basis of wear modes and friction. The module also deals with basic principles of tribology - the study of friction, wear, and lubrication - including the importance of materials, surfaces, design, operating conditions, environment and lubrication on friction, wear and surface damage in any system. Applications of tribological theories, concepts, techniques and approaches to design, research, development, evaluation, and problem solving are also included.
