  • Publication number: 20230314739
    Abstract: Exemplary embodiments are disclosed of thermal interface solutions for sliding surfaces. In an exemplary embodiment, a thermal interface material assembly includes a substrate having opposite first and second surfaces. An antifriction layer is along the first surface of the substrate. A thermal interface material is along the second surface of the substrate, such that the substrate is between the antifriction layer and the thermal interface material. The antifriction layer is configured to slide along in contact with a first surface of a first component when the thermal interface material assembly is along a second surface of a second component and when the first and second surfaces are slidably moved relative to each other.
