Evaluation method and manufacturing method for discharge surface treatment electrode, the electrode for discharge surface treatment, discharge surface treatment method and discharge surface treatment apparatus

摘要

Electrodes as (12), generates a discharge between the electrode (12) and workpiece (11), by the energy, the workpiece (11 a green compact by compression-molding powder of metal, ceramics or metal compounds electrode for discharge surface treatment used for the discharge surface treatment to form a (14) coating made of a material that the electrode material or the electrode material is reacted by the discharge energy to the surface) in (12), the powder, the average particle of 5~10μm a mixture of the components difficult to form or which has a diameter, does not form a carbide 40% by volume or more components to form the coating (12) to (11) the workpiece, and tested Ki pulled coatings pencil It is shaped to have a hardness in the range of hardness by B~8B.
