friction map (rus. карта трения) — graphical representation of the dependence between the friction coefficient and a combination of studied or controlled parameters (contact pressure, speed, temperature, etc.) obtained through experimental studies of the samples.


The most vivid representation is provided by 3D friction maps, in which the friction coefficient is represented as a surface of response to a set of variables, such as contact pressure, speed, temperature, etc. Depending on the purpose of friction mapping, other parameters can also be added, such as surface roughness, atmospheric composition, etc.

In the case of a 2D friction map, isolines of the friction coefficient are plotted on the plane of investigated parameters. It is useful to provide such maps with further information to shed light on experimental results. For example, in lubricant testing the maps can show the ranges of parameters, in which the lubrication rate is constant (boundary friction, hydrodynamic lubrication), or show the boundaries within which adhesion is observed.
