The pitting critical potential of the freshsurface is lower than that of the surface covered by passive film.
去膜表面发生点蚀的临界电位低于膜覆盖表面发生点蚀的临界电位。

The copper, the gold and the silver in the cyanide slag can better float in the floatation process after having freshsurface.
氰化渣中的铜、金和银有了新鲜表面后在浮选过程中能较好的浮游。

The wear volume was measured with 3D measuring instruments and the relationship between the freshsurface that fretting wear produces and worn surface was evaluated with the potential pulse method.
