Tribology and Surface Engineering


Book Description

The book covers very important issues, not only scientific in nature but, ultimately, for industry and the economy. Wear and deterioration of surface properties during operation is a natural and unavoidable phenomenon. However, minimizing the degree of wear is of great importance for the entire economy, as illustrated by the example of the US economy, for which the loss of natural resources as a direct cause of friction and wear exceeds 6% of the Gross National Product. This book showcases the valuable knowledge revealed from both theoretical and practical research results in the field of advanced technologies of coatings and surface modification, as well as wear and tribological characteristics of advanced materials and surface layers. Therefore, it is hoped that this book will be a valuable resource and helpful tool for scientists, engineers, and students in the field of surface engineering, materials science, and manufacturing engineering.

Advanced Techniques for Surface Engineering


Book Description

The hardest requirements on a material are in general imposed at the surface: it has to be wear resistant for tools and bearings; corrosion resistant for turbine blades; antireflecting for solar cells; and it must combine several of these properties in other applications. `Surface engineering' is the general term that incorporates all the techniques by which a surface modification can be accomplished. These techniques include both the more traditional methods, such as nitriding, boriding and carburizing, and the newer ones, such as ion implantation, laser beam melting and, in particular, coating. This book comprises and compares in a unique way all these techniques of surface engineering. It is a compilation of lectures which were held by renowned scientists and engineers in the frame of the well known `EuroCourses' of the Joint Research Centre of the Commission of the European Communities. The book is principally addressed to material and surface scientists, physicists and chemists, engineers and technicians of industries and institutes where surface engineering problems arise.
