ABSTRACT
This chapter describes the fundamental of tribology. Tribology is the
science and engineering of interacting surfaces with relativemotion.
Interacting areas can be found in machinery as well as human
body. In some contacting areas, low friction and wear are desirable
for requirements of high efficient and safe operation. Lubrication
is conducted to decrease friction and wear. On the other hand,
there also exist contacting areas in which high friction and wear
are required such as clutches, tires and erasers. It is important for
tribological engineers and scientists to control and use effectively
functions obtained from interacting surfaces such as friction, wear
and lubrication. In this chapter, the principles of friction, wear and
lubrication are introduced.
