1. Scope
This guide covers methods of extraction and analysis of particles in lubricating oils (both mineral based and synthetic) and phosphate ester fluids using Scanning electron Microscopy (SEM) and computer aided analysis using Automated Feature Analysis (AFA). This guide describes a method for determining the number, size and nature of contaminant and wear debris particles. The number and size of the particles is performed using high resolution SEM and a computer generated rotating cord algorithm. Identification of the elemental chemical composition uses SEM, electron beam.
To obtain maximum operating life and reliability, of lubricants and system, it is vital that wear debris and contamination levels be monitored on a regular basis. Monitoring the type of wear and contamination enables the user to be proactive in the maintenance of the monitored machine and lubricant.
