Coefficient of friction
The coefficient of friction, also called the adhesion load or the adhesion coefficient, describes the friction force or the value of the friction that arises between different material surfaces. It depends on several factors, such as the surface quality of the active surfaces, the surface treatment and, in the relevant case, the type of lubrication. For example, the higher the coefficient of friction, the better the braking behavior of brakes. However, it must also be noted that a higher coefficient of friction implies higher wear due to abrasion.
