Surface engineering is a multidisciplinary action intended to identify the properties of the surfaces of engineering mechanism in order to improve their function and serviceability. Corrosion, wear and fatigue are among the most important mechanisms that lead to materials degradation, which, eventually, leads to failure of components. Thus there is a great potential for saving resources, provided that the fundamentals of material behavior, and thus its performance including degradation, are understood, in order to define on that basis strategies to improve the intrinsic properties of materials. Carbon steel is commonly used in the industry but vulnerable to wear and corrosion in the field. Replacing it with stainless or alloy steel increases the cost significantly, and a better alternative is to improve its surface properties and lifetime using plasma immersion ion implantation.Thermochemical Surface Engineering of Steels deals with the treatment of the surface and near-surface regions of steel to allow the surface to perform functions that are distinct from those functions demanded from the bulk of the material. It deals with geometrical, optical and chemical properties of stainless steel surfaces polished by various methods. It highlights on nitriding thermochemical surface treatment used in steels and alloys to improve wear and friction properties by surface microstructure modification, while maintaining adequate substrate properties. Surface characterization and corrosion resistance of 36Cr-Ni-Mo4 Steel Coated by WC-Co cermet electrode is explained. Effect of heat treatment parameters on the mechanical and microstructure properties of low-alloy steel and effects of gas metal arc welding techniques on the mechanical properties of duplex stainless steel are discussed as well. It is hoped that this book will be of valuable for engineers and practitioners as well as for researchers and will inspire young people to donate to future growth in the field.

Research in the area of nanoindentation has gained significant momentum in recent years, but there are very few books currently available which can educate researchers on the application aspects of this technique in various areas of materials science. Applied Nanoindentation in Advanced Materials addresses this need and is a comprehensive, self-contained reference covering applied aspects of nanoindentation in advanced materials. With contributions from leading researchers in the field, this book is divided into three parts. Part one covers innovations and analysis, and parts two and three examine the application and evaluation of soft and ceramic-like materials respectively. Key features: A one stop solution for scholars and researchers to learn applied aspects of nanoindentation Contains contributions from leading researchers in the field Includes the analysis of key properties that can be studied using the nanoindentation technique Covers recent innovations Includes worked examples Applied Nanoindentation in Advanced Materials is an ideal reference for researchers and practitioners working in the areas of nanotechnology and nanomechanics, and is also a useful source of information for graduate students in mechanical and materials engineering, and chemistry. This book also contains a wealth of information for scientists and engineers interested in mathematical modelling and simulations related to nanoindentation testing and analysis.

This book presents the most important thermochemical and physical techniques of boriding. The formation and characterization of different boride layers or boride coatings are compared in this book. The author analyzes the technological aspects of boriding processes, presenting the advantages and disadvantages of each method. The effect of the boriding techniques on the microstructure of borided materials are also indicated. The mechanism of formation of active boron atoms or ions and the phenomena during re-melting of alloying material together with the substrate are described. Special attention is devoted to powder-pack boriding, electrochemical boriding in borax, gas boriding, plasma gas or paste boriding and laser or plasma surface alloying with boron, acknowledged as the most important current methods in boriding. The thermodynamics of gas boriding is also analyzed.

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.

This volume, the fruit of a current status seminar, reflects the enormous strides which have been made in the last few years in the study of the expanded austenite phase (also called the S phase) and the development of new surface treatment techniques. The book also contains a selection from related papers and a comprehensive bibliography of the literature on the subject from 1979 to 2000.

Surfaces are the bounding faces of solids. The interaction of component surface with the working environment results in wear and corrosion. Estimated loss due to wear and corrosion in the USA is around $500 billion. Engineered surfaces are the key to the reduction of losses due to wear and corrosion. There are surface engineering books on specific processes such as thermal spraying and vapor phase deposition or about specific heat sources such as plasma or laser. However, there are few, if any, covering the whole range of advanced surface engineering processes. Advanced Thermally Assisted Surface Engineering Processes has been structured to provide assistance and guidance to the engineers, researchers and students in choosing the right process from the galaxy of newer surface engineering techniques using advanced heat sources.

Austenitic stainless steels lend themselves to a wide range of applications. However, they normally stiffer from poor wear resistance and do not respond well to traditional surface treatments. This volume. the fruit of a current status seminar, reflects the enormous strides which have been made in the last few years in the study of the expanded austenite phase (also called the S phase) and the development of new surface treatment techniques. As well as the papers presented at the seminar, the book contains selection from related papers and a comprehensive bibliography of the literature on the subject from 1979 to 2000.
