Optical image of a scratch made with the edge of a cube
corner
shows the evolution of the pile-up height due to
visco-plastic relaxation after the scratch is made (for different systems
of automotive paints).

relaxation
Maintaining the same normal load, variation in scratch velocity results
in a variation of the scratch width. Faster motion results in a thinner
residual scratch, corresponding to a harder material.
