Answer 1

The 2 most commonly used solid lubricants are:

1.Graphite. Used in air compressors, food industry, railway track joints, brass instrument valves, open gear, ball bearings, machine-shop works, etc. It is also very common for lubricating locks, since a liquid lubricant allows particles to get stuck in the lock worsening the problem.
2.Molybdenum disulfide (MoS2). Used in CV joints and space vehicles.Does lubricate in vacuum.
