Wear metal analysis of lubricants has played an increasingly significant diagnostic role for condition monitoring of turbine engines in the Air Force since the Spectrometric Oil Analysis Program (SOAP) was adopted in the mid-1960's. Since introduction, SOAP has rapidly expanded with all services participating in a coordinated effort. SOAP has found general applicability in engine diagnosis, but not for all equipment, e.g., gearboxes and transmissions. Such mechanical systems can generate large wear debris that is not readily detectable using routine spectrometric techniques. This limitation has encouraged the continued use of chip detector and filter inspections, and the development of other monitoring techniques such as ferrography, to build a more complete assessment of mechanical condition for many applications. SOAP limitations as well as incentives to provide more timely data and improve cost effectiveness has generated support in various organizations to pursue development of improved laboratory, portable, in-line and on-line diagnostic systems. The current status and potential of these rapidly developing alternative technologies for future applications are reviewed and assessed.
