There are four phases in the standard scratch test. The first three are
shown across the top of
A first profile of the surface is realized by applying a very small load
1
(20 mN, for example), in order to have the original morphology of
the surface before the scratch.
Then, along the same path, the normal load is increased from the
2
starting scratch load (0 mN, for example) to the maximum scratch
load (200 mN, for example).
A last profile is realized by applying a very small load to measure the
3
residual deformation in the groove.
Finally, a profile across the residual scratch gives the shape of the
4
section of the groove and helps in evaluating the plastic deformation,
as shown on the bottom of
