Preface

Surface engineering was founded by detecting surface features which destroy most of pieces, e.g. abrasion, corrosion, and fatigue. Then it was recognized, more than ever, that most technological advancements are constrained with surface requirements. Considered re‐ quirements for surface were: increasing the strength against friction, abrasion, and corro‐ sion, or boosting the thermal, optical, magnetic, and electrical properties. For instance, fuel yield and specific output power of thermal engines, such as gas turbines or adiabatic diesels, is limited by hot corrosion and the properties of thermal barriers of special pieces of surfa‐ ces. Similarly, in a wide range of industry (such as gas and oil exploitation, mining, and manufacturing), the surface generates an important problem in technological advancement. Using total material for improving surface properties is not economically advised. Thus, for high rate of yield it is recommended to use a sub-layer with efficient properties, and materi‐ als which are cheaper and easier to reshape. Ideally, sub-layer must be optimized for maxi‐ mizing the coating benefits and, consequently, creating the most efficient coating system.

This just elucidates an aspect of surface engineering: products improving. Probably, the key importance of surface engineering is producing new materials, which are just resulted in advanced coating. Though electronic and optical electronic rigs are sharp examples, but nowadays most of mechanic engineering blocks are included in this topic. This book collects new surface engineering treatments and also advances in this science. I like to appreciate all of contributors to this book and thank them for their high quality manuscripts.
