Thermochemical Surface Engineering Of Steels

Thermochemical surface engineering significantly improves the properties of steels. Edited by two of the world s leading authorities, this important book summarises the range of techniques and their applications. It covers nitriding, nitrocarburizing and carburizing. There are also chapters on low temperature techniques as well as boriding, sheradizing, aluminizing, chromizing, thermo-reactive deposition and diffusion. Reviews the fundamentals of surface treatments and current performance of improved materialsCovers nitriding, nitrocarburizing and carburizing of iron and iron carbon alloysExamines how different thermochemical surface engineering methods can help against corrosion"

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.

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.

Annotation A practical selection guide to help engineers and technicians choose the mot efficient surface hardening techniques that offer consistent and repeatable results. Emphasis is placed on characteristics such as processing temperature, case/coating thickness, bond strength, and hardness level obtained. The advantages and limitations of the various thermochemical, thermal and coating/surface modification technologies are compared

This book focuses on the effect of plasma nitriding on the properties of steels. Parameters of different grades of steels are considered, such as structural and constructional steels, stainless steels and tools steels. The reader will find within the text an introduction to nitriding treatment, the basis of plasma and its roll in nitriding. The authors also address the advantages and disadvantages of plasma nitriding in comparison with other nitriding methods.

This highly illustrated reference work covers the three principal types of surface technologies that best protect engineering devices and products: diffusion technologies, deposition technologies, and other less commonly acknowledged surface engineering (SE) techniques. Various applications are noted throughout the text and additionally whole chapters are devoted to specific SE applications across the automotive, gas turbine engine (GTE), metal machining, and biomedical implant sectors. Along with the benefits of SE, this volume also critically examines SE's limitations. Materials degradation pathways - those which can and those which cannot be mitigated by SE - are rigorously explained. Written from a scientific, materials engineering perspective, this concise text is supported by high-quality images and photo-micrographs which show how surfaces can be engineered to overcome the limits of conventionally produced materials, even in complex or hostile operating environments. This book is a useful resource for undergraduate and postgraduate students as well as professional engineers.
