Friction and Wear
Methodologies for Design and Control
Mechanical components, manufacturing tools and the majority of engineering
systems with mating parts in relative motion may face serious failures due to wear
or unacceptable energy dissipations due to friction. The resulting costs are very
high, being a significant fraction of the GNPs of an industrialized nation, even if it
is a general feeling that large savings could be achieved with the adoption of
already existing design solutions, such as adequate choice of materials, appropriate
surface treatments, and scheduled maintenance programs.
The present text aims to provide an up-to-date overview of several aspects of
tribology and a theoretical framework to explain friction and wear-related problems,
together with practical tools for their solution. The basic concepts of contact
mechanics, friction, lubrication, and wear mechanisms are introduced, providing
simplified analytical relationships, useful for quantitative assessments. Subsequently,
the main wear processes are revised and guidelines on the most suitable
designing solutions for each specific application are outlined. The final part of the
text is devoted to the description of the main materials and surface treatments
specifically developed for tribological applications. Tribological systems of particular
engineering relevance are also presented.
The text is intended for students of undergraduate and graduate courses in the
fields of engineering, applied physics, and materials science, who must develop a
sound understanding of friction, wear, lubrication, and surface engineering. Also
technicians, researchers and professionals may find useful indications to solve tribological
problems related to their own work.
