Book Description
This monograph summarises results of research in some surface phenomena, observed in mechanical treatment and friction. In particular the book is devoted to urgent problems of the science of friction and wear and provides insight into the mechanism of the phenomena that cause, on the one hand, anomalously low coefficients of friction and wear (the so-called selective transfer) and on the other, dramatic damages of the surface layers during sliding (hydrogen wear of metals). The nature of metal interaction during sliding in selective transfer and hydrogen wear modes is analysed in detail. Furthermore results of studies concerned with certain aspects of phenomena appearing in the process of influencing contacting surfaces and with detecting the relationship between the observed characteristics and behavior of investigated materials in the process of mechanical treatment and friction are presented. The principle followed is to combine varied experimental facts, physical concepts and investigation methods, which at first sight appear to be unrelated, and using this approach to determine general rules. Chapter one provides the reader with a general understanding of fundamental surface phenomena which provide the background to their dynamic interaction in mechanical treatment and under friction. Chapter two deals with the laws governing influence of mechanical effects on the surface. The third chapter presents the fundamentals of the selective transfer theory under friction. Other chapters deal with the possibilities of the Mössbauer electron spectroscopy method, widely used in physics for solving tribology problems, the influence of external electromotive force sources on contact resistance and friction pairs' wear, and hydrogen wear of metals under friction.

Book Description
Surface phenomena in the field of high-temperature processes are attracting ever increasing attention on the part of scientific workers and engineers. In this field, many questions of applied science cannot properly be solved without taking into account the characteristics caused by surface phenomena at the various interfaces. The importance of surface phenomena in the pyrometallurgy of nonferrous and ferrous metals was convincingly demonstrated at a scientific conference on this problem held in Moscow towards the end of 1961. The English translation of the transactions of this conference, "Surface Phenomena in Metallurgical Processes, .. and its publication in the USA will ena ble American scientists and engineers working in the field of surface phenomena and metallurgy to acquaint themselves with the work of Russian investigators in this inter esting field of physical chemistry and the theory of metallurgical processes. In the Soviet Union, important groups of scientists in Moscow, Leningrad, Kiev, Sverdlovsk. and other cities are engaged in the study of surface phenomena as applied to the different branches of metallurgy. We trust that the publication of the American edition of the book "Surface Phenomena in Metallurgical Processes" will help to strengthen the scientific bonds between Soviet and American scientists.

Book Description
Fluid Flow Phenomena in Metals Processing outlines the fundamentals of fluid flow theory, emphasizing the potential applications of fluid flow concepts that are illustrated by actual problems drawn from the metallurgical literature. This book is divided into 10 chapters. Chapters 1 to 4 are devoted to the fundamentals of fluid flow, while Chapters 5 to 9 are concerned with the application of basic concepts to specific systems, such as electromagnetically driven flows, surface tension and natural convection driven flows, multiparticle systems, gas bubbles, and impinging jets. The discussion on flow measurements and introduction to physical modeling are provided in the last chapter. This publication is suitable for a one semester graduate level course for metallurgy and chemical engineering students.

Book Description
People seldom enjoy corrosion. They usually perceive it as a nasty phenomenon with which they must cope. Yet many people, far from the corrosion field, come across it because of their professional duty. Lawyers, historians, doctors, architects, philosophers, artists, and archeologists, to name a few, may want or need to understand the principles of corrosion. This volume explains this important topic in a lucid, interesting, and popular form to everybody: to students and young engineers who are only beginning their studies, to scientists and engineers who have dealt with corrosion for many years, and to non-specialists involved in corrosion problems. The book uses a fresh writing style, with some new explanations relating to thermodynamics of oxidation of iron and mild steels in water, reversible and irreversible potential, solubility of oxygen in water and aqueous solutions of electrolytes, corrosion of metals in fuels, corrosion of storage tanks for fuels and their corrosion control, corrosion monitoring in practice, humanitarian aspects of corrosion science and technology (history of the evolution of knowledge about corrosion, relationships between corrosion and philosophy, corrosion and art). Many practical examples of various corrosion phenomena are given.

Book Description
Surface Engineering of Metals provides basic definitions of classical and modern surface treatments, addressing mechanisms of formation, microstructure, and properties of surface layers. Part I outlines the fundamentals of surface engineering, presents the history of its development, and proposes a two-category classification of surface layers. Discussions include the basic potential and usable properties of superficial layers and coatings, explaining their concept, interaction with other properties, and the significance of these properties for proper selection and functioning. Part II provides an original classification of the production methods of surface layers. Discussions include the latest technologies in this field, characterized by directional or beam interaction of particles or of the heating medium with the treat surface.

Book Description
It is widely recognized that an understanding of the physical and chemical properties of clusters will give a great deal of important information relevant to surface and bulk properties of condensed matter. This relevance of clusters for condensed matter is one of the major motivations for the study of atomic and molecular clusters. The changes of properties with cluster size, from small clusters containing only a few atoms to large clusters containing tens of thousands of atoms, provides a unique way to understand and to control the development of bulk properties as separated units are brought together to form an extended system. Another important use of clusters is as theoretical models of surfaces and bulk materials. The electronic wavefunctions for these cluster models have special advantages for understanding, in particular, the local properties of condensed matter. The cluster wavefunctions, obtained with molecular orbital theory, make it possible to relate chemical concepts developed to describe chemical bonds in molecules to the very closely related chemical bonding at the surface and in the bulk of condensed matter. The applications of clusters to phenomena in condensed matter is a cross-disciplinary activity which requires the interaction and collaboration of researchers in traditionally separate areas. For example, it is necessary to bring together workers whose background and expertise is molecular chemistry with those whose background is solid state physics. It is also necessary to bring together experimentalists and theoreticians.
