Abstract
A component having a coating comprising a material in a first phase (e.g., solid and/or liquid phase) with a transition temperature. The component is mechanically and/or electrically attached to a substrate. Exposure of the coating to a temperature that meets or exceeds the transition temperature causes the material to undergo a phase change. The phase change of the material alters the position of the component, including separation of the component from the substrate. The separation disrupts the attachment, thereby mitigating damage to the substrate and/or component.
Claims10
A method comprising:
- configuring a component in communication with a substrate in a first position;
- applying a coating to the component, the coating comprising a material in a first phase having a transition temperature;
- subjecting the coating to a thermal event meeting or exceeding the transition temperature;
- responsive to the thermal event, subjecting the material to a phase change from the first phase to a second phase;
- and
- the phase change altering the position of the component from the first position to a second position, including the second position being a separation of the component from the substrate.
