Course Aims : Tribology is the science and technology of interacting surfaces in relative motion and of related subjects and practices. Understanding the nature of these interactions and solving the technological problems associated with the interfacial phenomena constitute the essence of tribology. The field of tribology incorporates a number of disciplines, including mechanical engineering, materials science, mechanics, surface chemistry, surface physics and a multitude of subject, design for tribology. The course aims at introducing students to the tribology and its components, and enabling them to use these in the designing, manufacturing and management phases.
