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 Scientific Group Thermodata Europe (SGTE) is a consortium of European and North American research groups developing thermodynamic databases and software to model the thermodynamic properties of metals and other materials. Understanding these properties is critical to improving the processing of metals and their performance in such areas as resistance to high-temperature corrosion. This substantially revised new edition explores both the theoretical background to thermodynamic modelling and its wide range of practical applications. These applications include the analysis of hot salt and other types of high-temperature corrosion, understanding the loss of corrosion resistance in stainless and other types of steel, the processing of steels, as well as the use of thermodynamics to improve the functionality of materials for microelectronics and lighting applications, and in the analysis of nuclear safety issues. New case studies also illustrate applications to kinetically-controlled processes such as the solidification and heat treatment of alloys as well as the production of silicon and titanium oxide pigment. The SGTE casebook is a valuable reference for those manufacturing steels and other materials, those using materials in high-temperature applications such as the power industry and in other areas such as microelectronics and lighting. This updated and revised edition explores theoretical background to thermodynamic modelling Practical applications are provided, including types of high-temperature corrosion Valuable reference for the power and microelectronics industry

This book intended for shop use tries to familiarize the reader with the peculiari ties of a hardening method which due to its many advantages is now in use,many shops. A general knowledge of the principles of hardening and heat treating is presumed. Introduction 1. The name of the process. Flame hardening is a method derived from the old quench hardening and is used for the surface hardening of heat treatable steels. Flame hardening is so named in analogy to flame cutting as the use of a flame is a distinctive feature of this process as opposed to the use of a furnace. 2. Characteristics of flame hardening. In flame hardening the area to be 6 hardened is heated with a burner of large heat capacity (approx. 0.5 · 10 kcaljhr/ meter of flame lengths or 50,000 BTUfhr/inch of flame length) supplied with a mixture of fuel gas and oxygen. The hardening temperature is thus reached in so short a time at the surface that a heat jam is created, that is, more heat is supplied to the surface than can be dissipated to the interior of the workpiece. As the querr ehing takes place immediately after the heating the penetration of the heat to greater depth is prevented and only the outer layer subject to wear is hardened. The core of the workpiece remains unaffected by this heat treatment in cantrast to the other hardening methods where the entire piece is through heated in a furnace.
