Molecular Basis of Lubrication

February 1, 2002
Author(s)
Stephen M. Hsu
Lubrication is an art that has been practiced for thousands of years from the early days of our human civilization. The study of lubricatin as a science began in the 17th century with the development of bearings and axles. In the early 20th century, the
