Method of manufacturing electrode for electrical-discharge surface treatment, and electrode for electrical-discharge surface treatment

摘要

A method of manufacturing an electrode for electrical-discharge surface treatment includes increasing oxygen content in the powder; mixing the powder, in which the oxygen content is increased, with an organic binder and a solvent to prepare a liquid mixture; granulating the powder in the liquid mixture to form granulated powder; and forming the granulated powder to prepare a compact in which an oxygen concentration ranges from 4 weight % to 16 weight %.

1. A method of manufacturing an electrode for electrical-discharge surface treatment used for electrical-discharge surface treatment for using a formed compact obtained by forming metal powder, metal compound powder, or conductive ceramics powder as an electrode, generating pulsed discharge between the electrode and a work in a working fluid or in the air, and forming a film on a surface of the work by energy of the pulsed discharge, the film being made of a material of the electrode or made of a substance with which the material of the electrode reacts, the method comprising:
increasing oxygen content in the powder; mixing the powder, in which the oxygen content is increased, with an organic binder and a solvent to prepare a liquid mixture; granulating the powder in the liquid mixture to form granulated powder; and forming the granulated powder to prepare a compact in which an oxygen concentration ranges from 4 weight % to 16 weight %.
