Structures including a measurement coating and methods of forming the same
| DWPI Title: Measurement coating forming method for e.g. airplane component, involves determining if behavioral change is present in response to excitation of substrate by controllable excitation source, and determining condition of substrate |
| Abstract: A structure includes a substrate and a coating applied over the substrate, the coating containing particles sized between 30 and 250 micrometers. A proportion of the particles to the carrier is between 40 and 70 by volume percentage. In response to excitation of the structure by a controllable excitation source, a first instrument monitors behavior of the particles to determine a first condition of the structure thereby. In response to an absence of excitation of the structure by the controllable excitation source, a second instrument monitors behavior of the particles to determine a second condition of the structure thereby. |
| Use: Method for forming measurement coating over structure. Uses include but are not limited to building, bridge, airplane component and component in other industries for cracks or structural flaws. |
| Advantage: The structure ensures that the entire component is being effectively vibrated with the ultrasonic horn, thus avoiding false negatives. The structure is suitable for applying to surfaces that are not relatively flat or uniform or continuous, and the tape size need not be larger than a predetermined minimum size to function properly. |
| Novelty: The method involves applying a coating comprising particles to a substrate. The particles initial behavior is measured to determine a first condition of the substrate. The substrate is excited by a controllable excitation source. The particles post excitation behavior and determining if there is a behavioral change is measured in response to the excitation of the substrate by a controllable excitation source. A second condition of the substrate is determined from the behavioral change. |
