Wear of Advanced Materials

Recent advances into the wear of advanced materials

In general, wear is currently defined as "the progressive
loss of material from the operating surface of a body occurring as
a result of relative motion at the surface". It is related to
surface interactions and more specifically to the form of contact
due to relative motion. Wear is rarely catastrophic but does reduce
the operating efficiency of machine components and
structures. At this time of economic crisis, this is a very
important field of study because of the huge impact the wear of
materials has on the economy.

The purpose of this book is to present a collection of examples
illustrating the state of the art and research developments into
the wear of advanced materials in several applications.

It can be used as a research book for a final undergraduate
engineering course (for example into materials, mechanics, etc.) or
as the focus of the effect of wear on advanced materials at a
postgraduate level. It can also serve as a useful reference for
academics, biomaterials researchers, mechanical and materials
engineers, and professionals in related spheres working with
tribology and advanced materials.

Recent advances into the wear of advanced materials

In general, wear is currently defined as the progressive loss of material from the operating surface of a body occurring as a result of relative motion at the surface. It is related to surface interactions and more specifically to the form of contact due to relative motion. Wear is rarely catastrophic but does reduce the operating efficiency of machine components and structures. At this time of economic crisis, this is a very important field of study because of the huge impact the wear of materials has on the economy.

The purpose of this book is to present a collection of examples illustrating the state of the art and research developments into the wear of advanced materials in several applications.
It can be used as a research book for a final undergraduate engineering course (for example into materials, mechanics, etc.) or as the focus of the effect of wear on advanced materials at a postgraduate level. It can also serve as a useful reference for academics, biomaterials researchers, mechanical and materials engineers, and professionals in related spheres working with tribology and advanced materials.
