Abstract
Vehicles and methods are provided for monitoring the health of a substrate and a protective coating disposed on the substrate. A vehicle includes a substrate, a protective coating, a coating deformation sensor, and a controller. The protective coating is disposed overtop the substrate. The coating deformation sensor is operatively coupled with the protective coating and configured to measure a deformation value of the protective coating. The controller is configured to: determine a deformation recovery rate of the protective coating based on the deformation value; determine whether the deformation recovery rate corresponds with an expected recovery rate of the protective coating; and indicate that the protective coating may be impaired in response to determining that the deformation recovery rate does not correspond with the expected recovery rate.
