Then, the potential is reversely swept in a downward direction to selectively corrode the crystal grain boundary part. In an active state region ranging from the self potential 1 to the passivation potential 2, sweeping is performed at a fast speed in order to activate the object part as the corrosion of all the crystal grains is being inhibited while sweeping is performed at a slow speed in time of the reverse sweeping in order to accelerate dissolution of the grain boundary part. The reverse sweeping is terminated at an arbitrary potential value after re-passivation minimum potential 8 is passed and until passivation maximum potential 2 is reached.  <P>COPYRIGHT: (C)2009,JPO&INPIT
