Lecture by prof. Dae-Eun Kim from Yonsei University in South Korea


Academic Centre for Materials and Nanotechnology invites for a seminary that will be held on 12th October, 2017, at 14.00 (2.00 pm).

A lecture titled Issues and Applications of Tribology will be given by prof. Dae-Eun Kim (School of Mechanical Engineering, Director Center for Nano-Wear, Yonsei University, Seoul, South Korea).

Venue: Kawiory 30 Street, building D-16, auditorium room 1.02A

An abstract of the lecture

Tribology is the science and technology regarding the phenomena that occur when two contacting bodies move against each other under an applied load. Namely, it deals with friction, wear and lubrication of all systems with moving parts such as automobile, machine tools, hard disk drives, human joints and MEMS. Since friction and wear are directly associated with energy consumption and waste of resources, there is a strong need to control these phenomena to achieve high efficiency and long life of machines. As such, extensive efforts have been devoted to understand and control friction and wear. In this talk, fundamentals of tribology will be presented including basic properties of solid surfaces and physical mechanisms. Particularly, the methods to reduce friction and wear by means of surface texturing and functional coatings will be discussed. Finally, as an example of how tribological interactions can be applied to other fields, mechano-chemical lithography will be introduced. This seminar will be helpful to those interested in surface engineering, and the contents will be sufficiently general to be understood by those with different background.
