41 papers provide a comprehensive overview of the problems andnew technologies in hydraulic systems associated with hydraulicfluids and their interaction with component design, componentmetallurgy, and the design of the hydraulic system itself.

Six sections cover: Theory, Mechanism and Simulation • FailureAnalysis • Materials • Components--Seals, Valves and RollingElement Bearings • Fluids

Major issues addressed include:

• The effect of fluid chemistry on component failure as theresult of oxidation, wear debris, viscosity loss, generation ofcorrosion by-products, and yellow metal wear.

• Metallurgy of the material, including material pair effectsand physical properties.

• The effect of surface finish.

• Modeling wear mechanisms as a function of material paircontact loading, speed, and other factors.

• Dynamic versus static wear.

• Wear mechanisms including rolling contact fatigue, cavitation,lubrication failure, abrasive wear, and others, in addition tocombinations of these mechanisms.

• Methods of failure analysis focusing on strategies to identifyroot caused of failure.

• Hydraulic component design and metallurgy of bearings, gears,slippers, and end-plates.
