  • Non-destructive mapping of surface condition to evaluate wear conditions
    Patent number: 9964399
    Abstract: A component, such as a cyclonic steam separator baseplate of a steam generator, includes a surface subject to degradation during operation of the system in which the component is disposed. A profile is acquired of the surface of the component using an optical surface profilometry system concurrent with an image of the surface. A condition, such as degradation of the component is classified based on the acquired profile and image of the surface of the component. Component conditions may be monitored over time, trended, and classified as requiring maintenance, repair, or replacement.
