Scanning Electron Microscopy for Wear Debris Analysis Oil analysis deploys various types of instru- ments, technologies, standards and tech- niques, all of which help provide a perspective on the health of the lubricant and the machine. e oil analysis data either targets specific properties of the lubricant, quanti- fies the level of various contaminants or directly measures any evidence of mechanical wear through wear debris analysis. Many concerns arise anytime solid debris (particulates) of any kind accumulate in the lubricant within a machine. On the one hand, if the solid debris is contamination-related, such as dirt or product debris entering the oil, this is a proactive (pre-failure) indicator that machine wear could occur as the debris becomes abrasive and disrupts the film thickness. While some amount of contaminant is expected, keeping this controlled is critical. On the other hand, if it's wear debris related, composed of metals such as iron or copper, this is a predictive (progressive failure) indicator that machine wear is already occur- ring, and action should be strongly considered if a functional failure is to be avoided. Monitoring for debris can be done in many ways. For example, daily visual inspection of the machine sight glasses or IIoT sensors can be the first indicator of abnormal conditions. Routine oil analysis can include tests to quantitatively look for particles in different ways, such as total particle size distribution (ISO particle counts), specific elements Factor: A7M Learn More: Factor: A7M – Troubleshooting and Root Cause Analysis Level: Management and Training(M) Stage: Condition Monitoring, Lubricant Analysis and Troubleshooting About: Taking the right approach to trouble- shooting and root cause analysis is critical for diagnosing problems quickly and finding sustainable solutions.
