2.1 Solid lubricant materials

Readers are referred to the article , § 3 M1 materials.

They feature the following characteristics:

• they are generally the most expensive;

• they have a static coefficient of friction close to the dynamic coefficient, which varies greatly depending on the load: the static coefficient is generally lower than that of lubricated materials; on the other hand, the dynamic coefficient is higher than that of lubricated materials;

• when used dry, they wear out and have a limited...
