摘要： An electrode is used to perform discharge surface treatment of a work piece. The electrode is made of a green compact obtained by compression-molding an electrode material including powder of any of a metal, a metallic compound, and ceramics. The discharge surface treatment includes generating an electric discharge between the electrode and the work piece in an atmosphere of a machining medium and forming a film consisting of a machining material on a surface of a work piece using energy produced by the electric discharge. The powder has an average particle diameter of 5 micrometer to 10 micrometers, and contains 40 volume percent or more of a component not forming or less easily forming carbide as a component for forming the film on the work piece. The electrode has a hardness in a range of B to 8B tested with a pencil scratch test for a coating film.

摘要： An electrode for an electrical-discharge surface-treatment method is molded with a metallic powder or a metallic compound powder having an average grain diameter of 6 micrometers to 10 micrometers. A coat on a surface of a workpiece is formed with a material constituting the electrode or a substance that is generated by a reaction of the material due to a pulse-like electrical discharge. The coat is built up with a material containing metal as a main constituent under conditions of a width of a current pulse for the pulse-like electrical discharge in a range of 50 microseconds to 500 microseconds and a peak of the current pulse equal to or less than 30 amperes.

摘要： To form a thick coating by a discharge surface treatment, a voltage between an electrode and a workpiece during a discharge is detected, and it is determined that a discharge surface treatment state is abnormal if it is detected that the voltage is reduced. With this arrangement, it is possible to accurately detect an unstable phenomenon in the discharge surface treatment, and take appropriate measures before a state of the coating and a state of the electrode are worsened due to the unstable phenomenon. By discriminating a stability of the discharge surface treatment, the coating and the electrode are prevented from being damaged.
