Summary

This second edition has 20% more scope, with four completely new chapters and eight existing ones completely revised to include more modeling, more industrial examples, new coating types, and new medical applications. Combining theory and practice from design to application, the monograph continues to provide a state-of-the-art treatise on plasma spray technology, beginning with the principles and techniques. Successive chapters treat the three important stages of energy transfer from the plasma to the surface, with modeling, depositing, testing and applying ceramic and metallic coatings covered in the shape of industrial problem solution examples. Concluding with quality control and a new section on biomedical issues and opportunities, the book offers pertinent knowledge for materials scientists, engineers, biologists and medical researchers alike.

Author Biography

Robert Heimann is professor emeritus of technical mineralogy and materials science. He obtained his academic degrees from Freie Universit+ñt (FU) Berlin, and subsequently served as a faculty member at FU Berlin and Universit+ñt Karlsruhe. From 1979 on he worked in Canada as a research associate (McMaster University), senior researcher (3M Canada Inc.), staff geochemist (Atomic Energy of Canada Limited), and research manager (Alberta Research Council). From 1993 to 2004 he was a full professor at TU Bergakademie Freiberg. Professor Heimann has authored over 260 scientific publications and in 2001 was awarded the Georg-Agricola-Medal of the German Mineralogical Society (DMG) for his outstanding lifetime achievements in applied mineralogy. He is now president of a consulting company and also on the editorial board of Elsevier's Surface and Coating Technology journal.
