Static friction is friction between two or more solid objects that are not moving relative to each other. For example, static friction can prevent an object from sliding down a sloped surface. The coefficient of static friction, typically denoted as s, is usually higher than the coefficient of kinetic friction.

Nov 27, 2008 Bulk on bulk coefficient values varied from just less than 0.7 to just over 1.0, typically (though not always) the respective tangent of the angle of repose for the various bulk materials, from soybeans, iron ore pellets, to 10 inch minus crushed ores. The additional load increments onto the bulk did not typically affect the friction coefficient.

Coefficient of static friction The coefficient of static friction (s) is defined as the ratio of the static friction force (f s) to the normal force of an element (F N) on a surface. 3 It is used to calculate the amount of force required to impart motion to an object that is initially at rest on another

Mar 04, 2005 A simple internal friction angle is the observed angle of repose of the stockpile. Usually, with bigger rock pieces this angle is in the rangle of 35-45 degrees, depending on how the pile is formed. This is not a friction angle. It is the dilation angle of particles moving on its surface rilling over one another.
As mentioned in the comments you dont want high friction between gear teeth, but if youre asking about the materials who exhibits higher friction with low wear rate, it depends on several parameters, such as, the nature of the two counterfaces, the environment, the applied load, the hardness, velocity, etc In general theres cubic crystal oxides, with a high hardness above 10GPA whom with ...
