摘要： An electrode (202) for discharge surface treatment is disclosed which is used in a discharge surface treatment wherein a compact body formed by compressing a metal powder, a metal compound powder or a ceramic powder is used as an electrode (201) and a discharge is generated between the electrode (201) and a workpiece (202) in a process liquid (205) or in the air for forming a coating film over the surface of the workpiece (202) with the energy of discharge. The coating film is composed of an electrode material or a material with which the electrode material is reacted by the discharge energy. In the electrode (202) for discharge surface treatment, the diameter of a material powder which is not desired to fuse is formed larger than that of another material powder which is desired to fuse.

摘要： As an electrode (12) an electrical discharge coating uses a green compact formed by pressing powder of a metal, a metal compound, or a ceramic or a heat-treated green compact. When, in a working liquid (15) or in an atmosphere, discharge is generated between the electrode (12) and a workpiece (11), the surface of the workpiece (11) is coated with a film (14) composed of the electrode material or a substance resultant from the reaction of the electrode material by the energy from the discharge. A method of evaluating an electrode (12) used for the electrical discharge coating is characterized in that the feasibility of film coating (14) using the electrode (12) is evaluated on the basis of the volume of an electrode material deposited on a workpiece (11) by a single pulse discharge.

摘要： In a rotating member (5) rotatably engaged with a housing (3), a pulse-like electric discharge is produced in a processing liquid or in a gas, between an electrode and the rotating member (5). The electrode is a chemical compound from metallic powder or metal, or a molded body formed by molding ceramic powder, or a molded body obtained by heating the molded body. Energy of the electric discharge causes coating to be formed on an engagement portion (15) engaging the housing (3), the coating formed from the material of the electrode or a substance to which the electrode material reacted by energy of the discharge.

摘要： A nozzle for processing machinery, wherein a hard ceramics coating is formed on the surface of the base metal of the nozzle for processing the machinery to prolong the service life thereof. Since the hard ceramics coating is formed on the surface of the base metal of the nozzle for the processing machinery, the nozzle for processing the machinery is hard to be scratched on the surface thereof and highly resistant to heat. Thus, service life can be prevented from being shortened due to the occurrence of scratch by the contact thereof with a warped work during processing and the deformation thereof by heat in the nozzle for processing the machinery to realize an increased service life.
