### Preface

In the past decades, significant advances in tribology have been made as engineers strive to develop more reliable and high performance products. The advancements are mainly driven by the evolution of computational techniques and experimental characterization that leads to a thorough understanding of tribological process on both macro- and microscales. Although great strides have been made in tribology, there are imminent challenges for researchers in the 21st century to develop more environmental friendly and energy efficient technology. The purpose of this book is to present recent progress of researchers on the hydrodynamic lubrication analysis and the lubrication tests for biodegradable lubricants.

The book comprises three sections. The first section, Hydrodynamic Lubrication, covers the fundamental aspects of hydrodynamic lubrication modeling and analysis. It consists of five chapters including theory of tribo-systems, hydrodynamic lubrication analysis of heavy-loaded tribounits lubricated with non-newtonian fluid, tribological aspects of rolling bearing failures, bearing friction of compound planetary gears, and the three-dimensional stress calculation of a damaged pipe under complex loading. The second section, Lubrication Tests and Biodegradable Lubricants, covers recent development of biodegradable lubricants. It consists five chapters including lubricity of RBD palm olein, biodegradable lubricants and production via chemical catalysis, lubricating greases based on fatty by-products and jojoba constituents, and characterization of lubricant on ophthalmic lenses. The third section, Solid Lubricant and Coatings, covers the applications of solid lubricants and surface coatings to wear resistant. The section includes investigation of tribological behavior of solid lubricants in hydrogen environment, alternative Cr+6-free coatings sliding against NBR elastomer, and the new methods for scuffing and pitting investigation of coated materials for heavy loaded, lubricated elements.

I wish to sincerely thank the authors for writing comprehensive chapters on a tight schedule. I would also like to express my sincere appreciation to the publisher, and in particular to Ms. Iva Simcic for her patience and excellent cooperation.
