Abstract
A downhole tool includes a component that is configured to dissolve in a wellbore fluid, and a protective coating applied to the component. The protective coating is configured to isolate the component from the wellbore fluid, and to fracture in response to the component deforming and expose the component to the wellbore fluid.
