This text focuses on the characterization of surface integrity and its influence on the functional performance of manufactured components. The book, now published in paperback, is a reprint of the work originally published in 2001 by Penton Press. The content is appropriately aimed at senior undergraduate and postgraduate manufacturing students. However, it would also be suitable for materials or mechanical engineering students and a useful reference for more experienced engineers who do not posses expertise in surface-finishing technologies or characterization of surface integrity.
The concept and importance of surface integrity is rigorously outlined and placed in appropriate context. The text breaks surface treatment technologies into fundamental unit events (chemical, thermal, thermo-mechanical, and mechanical) and relates these unit events to the resulting surface integrity. These surface effects are then related to the component’s performance, including mechanical strength, fatigue, and corrosion resistance. Throughout the text, numerous industrial examples are citied and everyday analogies used to put microstructural features into context.
The text focuses principally on turning, grinding, abrasive jet machining, and electrical discharge machining, using these techniques as general examples of the numerous surface-finishing technologies. The characteristics of the surfaces produced by each method are related to the process via the unit events. The author also explains the effect of gentle, conventional, and abrasive machining for each of the surface machining processes.
A range of topographical characterization techniques is described, with particular focus on profilometry, and the appropriate methodologies for applying them are explained. Unlike some other works, this book describes more than the standard Ra values, giving both verbal and mathematical descriptions of a selected range of parameters. In addition to the conventional two-dimensional profilometry, a concise description of three-dimensional (3-D) profilometry and the associated parameters is given. The author also explains the advantage and potential pitfalls of 3-D techniques. The effect of the defined unit events on the topographical features is adequately covered and a number of specific examples cited.
In addition to the topographical effects, the book also discusses the materials changes that occur at and beneath the surface. The effects different machining processes and conditions have on the material and the formation on sub-surface layers are examined. The importance of residual stress and its relationship to the unit events is covered, with an emphasis on the effects on performance of the components.
The text is an excellent source of references for those new to the field, providing accurate citations of many of the seminal texts in appropriate context. The frequent references to practical examples and appropriate references demonstrate the author’s in-depth knowledge of the subject. The last section of the book is concerned with standards and provides a good starting point for further investigation and for designing experiments. Students will also find the special feature on typical examination questions extremely useful.
Brian Griffiths of Brunel University, United Kingdom, is one of the recognized experts in the field; his extensive experience and knowledge are reflected throughout this up-to-date, concise text.
