Using SEM/EDS Technology for Better Wear Debris Analysis

Scanning electron microscopy/energy-dispersive spectroscopy (SEM/EDS) can be an effective method of wear debris monitoring to help prevent equipment failures. Modern SEM/EDS has evolved to enable automated analysis and processes, which are key techniques in circumventing the technical challenges involved in selecting the right tools to perform a proper analysis in a timely and economical manner. The following three case studies will show how SEM/EDS technology can successfully resolve tough analytical problems using particle sizing and characterization, wear debris analysis and filter debris analysis.

  • Oil Clotting and the Adrenaline Effect

    We are all familiar with blood clotting and its role in constricting blood flow after injury. Clotting depends on the coagulation of platelets and blood cells aided by fibrin molecules to trap and bind them together. This coagulated mass effectively plugs capillaries to stop uncontrolled hemorrhaging and bleeding.   Read

  • Hydrodynamic Cleaning and Flushing of Turbine Oil Systems

    One of the most important but underestimated factors impacting the operation of turbines (both steam and gas) and other machinery is the condition of the oil, especially its “mechanical” cleanliness (presence of solid particles). Although the need for appropriate oil care is commonly accepted among power plants with regular maintenance

  • Distinguishing Regulators and Reducing Valves

    We have seen a lot of confusion about pressure reducing valves and regulators in fluid power systems. This confusion is largely due to the nomenclature and partly because the schematic symbols are not always as intuitive as they could be.   Read more
