Beschreibung
Zusammenfassung:	Elektrode für eine Funkenerosionsoberflächenbehandlung, umfassend einen Grünling, der durch Komprimieren von Pulver eines Elektrodenmaterials gebildet ist,wobei das Pulver des Elektrodenmaterials ein gemischtes Pulver ist, das durch Mischen von 10 bis 75 Vol.-% von Si Pulver zu einem Pulver eines Hartstoffs gebildet ist,wobei das Pulver des Hartstoffs TiC ist. In order to establish an electric-discharge surface treatment capable of forming a smooth high-hardness coating, in the electric-discharge surface treatment in which pulsed electric discharge is generated between the electrode and a base material in a machining fluid or in the air by using a green compact, which is formed by compressing powder of an electrode material, as an electrode, and by using energy of the electric discharge, a coating including the electrode material or a reaction product of the electrode material reacted by the electric discharge energy is formed on a surface of the base material, wherein, as the powder of the electrode material, a mixed powder formed by mixing 10 to 75 vol % of Si powder to powder of a hard material is used.
