drylubricant
Dry lubricant is a solid material designed to reduce friction and wear between two sliding surfaces in the absence of liquid lubricants. It forms a thin, adherent film that remains on contact surfaces during motion, enabling smoother operation and longer life in dry or vacuum environments. Common dry lubricants include layered materials such as graphite and molybdenum disulfide (MoS2); others comprise fluorinated polymers like PTFE (Teflon), boron nitride, and tungsten disulfide. These materials are chosen for their low shear strength between layers, chemical stability, and ability to function at high temperatures or under clean-room conditions.
Performance depends on the material and the environment. Graphite and MoS2 excel in dry, inert conditions and
Applications include bearings, gears, seals, sliders, and vacuum equipment in aerospace, automotive, and industrial settings. They
