Course Objectives:

• To educate the students on theimportance of friction, the related theories/laws of sliding and rolling friction and the effect of viscosity of lubricants.
• To expose the students to the consequences of wear, wear mechanisms, wear theories and analysis of wear problems.
• Tomake the students understand the principles of lubrication, lubrication regimes, theories of hydrodynamic and the advanced lubrication techniques.
• To expose the students to the factors influencing the selection of bearing materials fordifferent sliding applications.
• To introduce the concepts of surface engineering and its importance in tribology.
