Erosion wear
Introduction
In materials science, wear is the erosion of material suffered by a solid surface by the action of another surface. It is related to interactions between surfaces and more specifically to the removal of material from a surface as a result of mechanical action.[1] The need for mechanical action, in the form of contact due to relative motion, is an important distinction between mechanical wear and any other process with similar results.[2].
Phases or stages
Under normal operating parameters, changes in properties during use normally occur in three different stages, which are:
Guys
The study of wear processes is part of the science of tribology. The complex nature of wear has delayed its study and has directed it towards specific wear mechanisms or processes.[3] Some specific wear mechanisms (or processes) are:
In addition to the above, there are other types of wear commonly found in specialized literature such as; Impact wear, cavitation wear, diffusive wear and corrosive wear.
