Wear and corrosion resistant coatings by CVD and PVD
Wear and Corrosion Resistant Coatings by CVD and PVD Edited by H K Pulker The modification of surface properties by the application of coatings provides a potent means of improving wear resistance, reducing friction, preventing corrosion and changing the surface appearance of materials. Several methods of surface engineering have been developed intensively over the past twenty years or so, and now find widespread industrial application. This book offers a survey of some important current methods of surface coating and modification and their applications, and is intended for undergraduates, postgraduates and research workers in metallurgy, chemistry, physics and mechanical engineering. The ten chapters, each by a differem author, constitute an English translation of a book originally published in German in 1985. Its multiple authorship, translation from German and date of original publication all unfortunately give rise to problems. Eight of the chapters deal with the formation of coatings by chemical and physical vapour deposition (CVD and PVD) and their properties, with the remaining two chapters devoted to the technology ol vacuum plasma spraying and ion

beam methods of surface modification. Most of the chapters are written as self-contained reviews by authors active in the surface engineering industry; there is, however, little evidence of consultation between them on subject matter, or of strong overall editorial direction, with the result that there is considerable overlap in the coverage of topics between the different authors. For example, no fewer than six chapters review to varying extents the range of available PVD processes, so that a reader seeking a critical overview is bewildered by choice. In most of the areas covered the emphasis of the book is heavily empirical and technological, with little explanation of the scientific principles underlying the deposition processes or the properties of the coatings. The standard of translation into English is variable, but in much of the book is very poor, making the text difficult to digest and in some places even downright incomprehensible. The layout and typography are also of low quality, with the text fragmented by poor placement of figures and tables, and on average at least one glaring typographical error on every page. The lists of references for each
chapter provided at the end of the book are disparate in style and format, with some entries incomplete and others still untranslated from their original German. As might be expected in a book first published in 1985 and only slightly revised for this English edition, nearly all the references are to work published in or before the early 1980s: this is unfortunate in a recently published book on such a rapidly developing subject area. The index, running to a mere half page of entries, is almost completely useless. 1 had hoped, having read the publisher's comments on this book. to be able to recommend it to the tyro looking for an introduction to surface coating technology, Regretfully~ I cannot do so. Readers with research interests in the properties and producthm of surface coatings, or thosc already working within the industry on technological aspects of surface processing, may find some value here, especially in the rcferences to more detailed publications. However, this book is like the curate's proverbial egg: the nutritious parts are unfortunately somewhat overpowered by the indigestible.
