A New Era: Wear Particle
Analysis/ Ferrography
Wear particle analysis, or ferrography, is a technique that is growing
everyday. With industrial needs for reliability and higher productivity to
compete in the world market, techniques such as wear particle analysis become
vital in making diagnostic and specific recommendations regarding potential
machine problems.
Having
wear particles provide evidence of machine problems depends on the industrial
application from a clean environment to a dirty one. However, showing
photographic proof and describing the surface texture, size, shape, and
morphology of the particles gives us evidence that something is potentially
wrong with the machine prior to major damage. This article will describe
improved ferrographic instrument design utilizing the new ASTM Standard
description for wear particles. Additionally, we will review the basic
operating process for utilizing ferrography to pinpoint any machine condition
issues.
