While the tribology is generally considered as related to mechanical engineering and design, the ever-increasing demand for the development of advanced materials for tribological applications necessitates a methodical understanding of tribology in materials science perspective. The proposed course is designed to provide knowledge on basic concepts of tribology as well as to understand the state of the art findings in friction and wear for a range of advanced material systems. The microstructure-properties-performance relationship is highlighted in understanding the behavior of the material in given wear conditions. Assignments on qualitative as well as quantitative understanding of tribology concepts will be provided.       INTENDED AUDIENCE:Interested studnets PREREQUISITES : None INDUSTRY SUPPORT : Industries dealing tribology: DUCOM, Bangalore
