Wear Debris Analysis

With over 70 illustrations, figures and tables, this book is a very inclusive reference. It gives a practical look at wear debris and wear particle analysis in many forms.   Author: Brian J. Roylance and Trevor M. Hunt Format: Hardback Pages: 127 Excerpt: Trend Analysis "Trend Analysis is the process by which a change in machine condition is determined from an examination of changes in specific sensors or output. "Different systems exhibit different trends. For instance, the wear debris generated from a system involving gears and bearings may well be quite high initially, particularly if no attempt has been made to 'run-in' the system. Thus there is a gradually reducing level of debris until the system settles in. Then comes the acceptable very low wear rate associated with well lubricated surfaces, which perhaps increases just slightly. Finally, the machine begins to show signs of fatigue or fracture and particle generation increases at an ever increasing rate. These th
