Lubrication Technology course is an elective course, introducing tribology, with the topic of friction and wear phenomena on two moving solid surfaces, characteristics of liquid and solid lubricants, the effect of variable speed, load and viscosity on lubrication modes (hydrodynamic, elastrohydro-dynamic lubrication) with the help of the Stribeck curve. Understanding the advantages/ disadvantages of mineral oil compared to synthetic oil and vegetable lubricants. Technology to improve lubricant performance by utilizing additives, including how they work, and their formulations. Technology to improve lubricant performance by modifying the structure of the base lubricant. Lubricant degradation and contamination, lubricant monitoring and maintenance and processing of used lubricants
