Friction, Wear, Lubrication: A Textbook in Tribology
Surface roughness usually has little or no consistent effect on the coefficient of
friction of clean, dry surfaces. Rough surfaces usually produce higher coefficients
of friction in lubricated systems, particularly with soft metals where lubricant films
...
This limiting value is a definite fraction of FV, and the ratio Ff/Fv is called the
coefficient of friction, n. Therefore, FF = nFv. For dry, rigid surfaces, n is affected
little by the area of the surfaces in contact or the magnitude of Fv. When surfaces
start ...

Surface effects in adhesion,
friction, wear, and lubrication
Removing adsorbates (or oxides in a case of metals) results in an increase in the
coefficient of friction; that is, clean, solid material surfaces exhibit higher friction
coefficients than do those containing contaminants. This is demonstrated in table
...

Friction and Lubrication in Mechanical Design
load appears to have no direct effect on the coefficient of friction in the thermal
regime. Rolling speed is found to have a significant effect on the coefficient of
friction in pure rolling conditions and in the isothermal, the nonlinear, and the
