Plasma Jets In The Development Of New Materials Technology

The demands of industry for creating new functional materials with predetermined properties have stimulated an increasing interest in the investigation of processes occurring in plasma jets of complex chemical composition (homogeneous and heterogeneous) as well as their interaction with hard surfaces. This Proceedings volume contains contributions from leading international specialists on plasma science and technology which were presented at the 2nd International Workshop ''Plasma Jets in the Development in of New Materials Technology'', 3--9 September 1990, Frunze (USSR). The scope of the workshop incorporated the following aspects: -- modelling of the processes of momentum heat and mass transfer in homogeneous and heterogeneous plasma jets as well as interaction between the particles and the base; -- diagnostics of the parameters of gas and disperse phases in plasma flows; -- plasma-spraying processes investigations; -- processes of treatment and production of materials, including powder materials.

Volume 1 of a two-volume work publishes studies of scientific from a number of countries in the area of plasma torch design and properties. Topics covered include mathematical modelling of transformer discharge, physical phenomena in a hollow cathode, modelling of electric arc plasma, problems of turbulent arc modelling, erosion of multiarc cathodes, integrated methods of research of processes in thermal plasma, trends in thermal plasma technology, plasma metallurgy, analysis of induction plasma systems, and many others.

This fully revised, industry-standard resource offers practical details on every aspect of the fundamentals necessary for understanding thermal spray technology, from powder all the way to the final part. The second edition is presented in a reader-friendly format that is split into four parts. Part I presents a review of thermal spray coating and its position in the broad field of surface modification technologies. Highlights of combustion and thermal plasmas are given with an expanded treatment of in-flight plasma-particle interactions. The second and third parts deal respectively with an updated presentation of thermal spray technologies and coating formation, including solution and suspension plasma spraying. The last part of the book includes a comparative analysis of different thermal spray processes, which is essential for the optimal selection of the appropriate thermal spray process in a given application. Coverage of system integration has been expanded with the addition of a detailed discussion of online instrumentation and process diagnostics and numerous examples of industrial scale spray booth designs. Attention is also given to coating finishing and health and safety issues. An extensive review is presented of thermal spray applications grouped in terms of process objectives and present use in different industrial sectors. This book will serve as an invaluable resource as a textbook for graduate courses in the field and as an exhaustive reference for professionals involved in the thermal spray field.
