An in situ wear measurement system has been demonstrated for steam turbine applications. The diagnostic technique can measure the wear and erosion damage caused by solid particle erosion (SPE) on a main steam stop valve bypass valve disc (SVBV). The technique consist of weakly activating the areas o...
