mm3 N-1 m -1 when the sliding electric current, speed and normal pressure respectively were set
to 100 A, 60 m s -1 and 0.6 MPa. The low friction coefficient can be attributed to the presence of
a continuous frictional oxide film consisting of an amorphous mixture of Al, Ti and Fe oxides on
the friction surface, which have a significant antifriction effect on the friction surfaces. The
percentage of oxide film cover was relatively higher when the electric current was 0 A, while the
percentage of oxide film cover decreased with increasing electric current. The increase in the
wear rate was ascribed to the ablation of the electric arc when the electric current was high. ©
