2. Grease (lubricant) - Wikipedia

   en.wikipedia.org/wiki/Grease_(lubricant)

   The grease helps to prevent joints from "freezing", as well as ensuring high vacuum systems are properly sealed. Apiezon or similar hydrocarbon based greases are the cheapest, and most suitable for high vacuum applications. However, they dissolve in many organic solvents.

3. Vacuum grease - Wikipedia

   en.wikipedia.org/wiki/Vacuum_grease

   As well as a lubricant, vacuum grease is also used as a sealant for joints in vacuum systems. This is usually limited to soft vacuums, as ultra high vacuum or high temperatures may give problems with the grease outgassing. Grease is most commonly used with glass vacuum systems. [1] All metal systems usually use knife-edge seals in soft metals ...

4. Dry lubricant - Wikipedia

   en.wikipedia.org/wiki/Dry_lubricant

   Pastes are grease-like lubricants containing a high percentage of solid lubricants used for assembly and lubrication of highly loaded, slow-moving parts. Black pastes generally contain MoS 2 . For high temperatures above 500 °C, pastes are composed on the basis of metal powders to protect metal parts from oxidation necessary to facilitate ...

5. Molybdenum disulfide - Wikipedia

   en.wikipedia.org/wiki/Molybdenum_disulfide

   Few alternatives exist that confer high lubricity and stability at up to 350 °C in oxidizing environments. Sliding friction tests of MoS 2 using a pin on disc tester at low loads (0.1–2 N) give friction coefficient values of <0.1. [35] [36] MoS 2 is often a component of blends and composites that require low friction.

6. Materials for use in vacuum - Wikipedia

   Austenitic stainless steels are the most common choice for high vacuum and ultra-high vacuum systems. Not all alloys are suitable; e.g. the free-machining 303 steel contains sulfur, which tends to outgas. Alloys with good weldability under argon arc welding are usually chosen. 304 stainless steel is a common choice of a stainless steel.

7. Silicone grease - Wikipedia

   en.wikipedia.org/wiki/Silicone_grease

   Silicone grease, sometimes called dielectric grease, is a waterproof grease made by combining a silicone oil with a thickener. Most commonly, the silicone oil is polydimethylsiloxane (PDMS) and the thickener is amorphous fumed silica. Using this formulation, silicone grease is a translucent white viscous paste, with exact properties dependent ...
