5 mol/L H2SO4 solution at different potentials and in air were investigated using a pendulum scratching apparatus, the hydrogen contents in scratching tracks was measured with SIMS, and the morphologies of scratching tracks were observed by SEM.

In order to extend its application scopes,this paper introduces the principle of single-pass pendulum scratching test and its applications to test wear resistance of conventional metallis materials,ductile-brittle transition of quasi-brittle materials,wear resistan.

The adhesion was measured by direct pull-off tests and by single pendulum impacting scratch tests.
