What Are Lubricants?

Definition Lubricant is a substance which is used to control (more often to reduce) friction and wear of the surfaces in a contact of the bodies in relative motion [1]. Depending on its nature, lubricants […]

galled specimen

What is galling? Severe types of adhesive wear are often referred as galling, scuffing, welding or smearing, although these terms are sometimes used loosely to describe other types of wear. In metal-to-metal wear tests, high […]
