Abstract
A pulsed discharge is generated between tip ends of a rotating member such as a blade and a discharge electrode including a hard material such as cBN in dielectric liquid or gas by a power supply for discharge to melt the discharge electrode, and a part of the discharge electrode is attached to the tip end of the rotating member to form an abrasive coating film including the hard materials such as cBN.
