WebMay 4, 2024 · For car batteries, there is terminal grease, which basically is a simple grease with corrosion inhibitors. Since it is an insulator, some pressure is required to make a good electrical connection between the contacts. This pressure makes this grease less optimal for small connectors with lighter contacts. Here, oily contact sprays are better. WebMay 26, 2024 · Since a contact between the graphite flake and its surroundings occurs through two incommensurate graphitic interfaces, and is thus superlubric ( 6 ), there should be a critical load, N, above which the generated lateral squeezing force, Fsq, is strong enough to break the edge bonds. cumberland county nc sheriff\u0027s office phone
