The study of wear, friction and lubrication, as part of the science and technology of inter-acting surfaces, are encompassed by the term tribology. Wear resistance is not an intrinsic material property. Many industrialists hope for a wear test equivalent of the hardness or tensile test and it remains diffiCult for some to understand
wear resistance due to the different microscopic mechanisms of wear occurring in abrasion. The questions are: where are abrasive wear likely to occur? When do these forms of wear occur and how can they be recognized? What are the differences and similarities between other types of wear? Key words tribology
type of contact, etc. All mechanical, physical, chemical, and geometrical aspects of the surface contact and of the surrounding atmosphere affect the surface interactions and thereby also the tribological characteristics of the system. Therefore, friction and wear are not simply materials parameters available in handbooks; they
Fundamentals of Wear Failures. Raymond G. Bayer, Tribology Consultant. Examination and Characterization of the Tribosystem. Wear is a system characteristic or phenomenon; it is not a materials property. Materials wear differently in different wear situations, and different materials wear differently in the same situation.
Introduction to Wear. • Plastic deformation at the interface often leads to wear, i.e., deformation induced wear. • Wear can also be caused by chemical processes. • There are many different kinds of wear mechanisms. • We have to analyze these wear mechanisms using mechanics, thermodynamics, etc. Tribology is a.
A wear map is considered one of the best descriptions of tribological conditions and is useful in selecting materials in a wide range of operating conditions. In order to design tribosystems and select materials based on the wear map, an understanding of wear rate, varieties of wear modes, and wear mechanisms is essential.

Wear is related to interactions between surfaces and specifically the removal and deformation of material on a surface as a result of mechanical action of the opposite surface. In materials science, wear is erosion or sideways displacement of material from its "derivative" and original position on a solid surface performed by
The amount of material worn in a tribological system is measured in relation to the duration and extent of contact. Specifically, a common measure of wear is the volume of material removed per unit sliding distance. Consider a tribological system where a volume. Vw of the softer component of the couple is removed by wear
means there are more than 35 types of wear. Q.3. In a tribological system where two tribo-surfaces are moving at relatively high speed, should the design of such system involve the use of similar metals or dissimilar metals to prevent adhesive wear and seizure? Ans: Whether low or high speed, molecular attraction,
