Modern Applications of Tribology - AS

Tribology is defined as the study and application of the principles of friction, lubrication and wear. In the early 1960s, there was a dramatic increase in the reported failures of plant and machinery due to wear and associated causes. Tribologic principles were used to address these industrial issues. Today, those principles are being applied in a variety of modern applications, such as ...
