The purpose of this paragraph is simply to highlight the aspects that will influence the choice of materials.
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...
