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

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.

A new method,single pendulum scratching test, as well as the tester, to evaluate adhesive strength between plating and substrate is introduced.

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.

The residual stress of weld,in both parallel and perpendicular direction,was measured by impacted indentation method for hybrid laser-tungsten inert gas arc welding of magnesium alloy.
