Tribology of Ceramics and Composites provides a rigorous study of how materials science can be used to understand, explore, and harness tribological interactions. Including introductory chapters on the fundamentals, processing, and applications of tribology, the book in designed primarly to provide students and practicing scientists with a comprehensive understanding of the fundamentals of the nature and properties of ceramic and composite materials as well as the friction and wear of sturctural ceramics in unlubricated, water-lubricated, and cryogenic enviroments. This book also includes thematic sections on tribological properties of bioceramics, biocomposites, and nanoceramics, as well as lightweight composites.

One of the alternative hydraulic fluid is water, which is environmentally acceptable, low-cost and non-flammable. We have designed a new hydraulic testrig and a new water proportional control valve to investigate the tribological and hydraulic behaviour of such water-based systems under pressures of up to 16 MPa and flows of up to 30 lpm. In this work, we present the lifetime performance of all-stainless-steel valve with distilled water being used as the hydraulic fluid. The results show that the water-based valve can operate for more than 10 million cycles under industrial relevant conditions if the water cleanness is appropriately maintained.

Controlling of the frictional properties of contact surfaces is becoming more and more important due to constant demands for improving the reliability and efficiency of mechanical parts and particularly for friction reduction. In recent years, surface texturing was established as a surface engineering technique for friction reduction. The reduction of friction was achieved by producing a variety of patterns in the form of micro-wells or grooves on the surface. Change of texturing parameters, such as shape of the wells and grooves, their depth and width, density and orientation, that affect the friction and wear in boundary lubrication regime is still largely based on trial and error procedure. An idea to design contact surfaces which would result in lower friction is to consider the textured surfaces as orderly surface roughness...
