Component failures result from a combination of factors involving materials science, mechanics, thermodynamics, corrosion, and tribology. With the right guidance, you don't have to be an authority in all of these areas to become skilled at diagnosing and preventing failures. Based on the author's more than thirty years of experience, Practical Plant Failure Analysis: A Guide to Understanding Machinery Deterioration and Improving Equipment Reliability is a down-to-earth guide to improving machinery maintenance and reliability.
Illustrated with hundreds of diagrams and photographs, this book examines…
- When and how to conduct a physical failure analysis
- Basic material properties including heat treating mechanisms, work hardening, and the effects of temperature changes on material properties
- The differences in appearance between ductile overload, brittle overload, and fatigue failures
- High cycle fatigue and how to differentiate between high stress concentrations and high operating stresses
- Low cycle fatigue and unusual fatigue situations
- Lubrication and its influence on the three basic bearing designs
- Ball and roller bearings, gears, fasteners, V-belts, and synchronous belts
Taking a detailed and systematic approach, Practical Plant Failure Analysis: A Guide to Understanding Machinery Deterioration and Improving Equipment Reliability thoroughly explains the four major failure mechanisms-wear, corrosion, overload, and fatigue-as well as how to identify them. The author clearly identifies how these mechanisms appear in various components and supplies convenient charts that demonstrate how to identify the specific causes of failure.
- Presents practical guidance on failure mechanisms, what leads to these failures, and how to avoid them in the future
- Integrates aspects of mechanics, corrosion, materials science, and tribology into a clear and concise approach
- Provides easy-to-follow charts that help you logically diagnose a failure and take appropriate corrective action
- Supplies more than 300 photographs and illustrations that help build confidence and competence in visual diagnosis
- Contains a clear and detailed explanation of the differences between through- and case-hardened gear teeth

As every reliability professional has seen, another area where the value of failure analysis commonly isn't utilized involves the practice of routinely scheduled outages. Should maintenance be scheduled based on the position of the sun or the moon and end up with monthly or annual outages? What is the real difference between a scheduled outage and a breakdown? The need for maintenance has to be recognized but in many cases the time between these "scheduled failures" can be greatly lengthened by analysis of the need for the various phases of the outage. We have never seen a situation where, after a competent and detailed analysis, the time between outages hasn't been increased by at least 50%.
