摘要： A sliding surface of a high-temperature portion is subjected to an electro-discharge surface treatment with one or both of a high-temperature hard material (4) and a material having a lubricating property at a high temperature (6). The high-temperature hard material (4) is any or a mixture of cBN, TiC, TiN, TiAlN, TiB2, WC, Cr3C2, SiC, ZrC, VC, B4C, Si3N4, ZrO2, and Al2O3. The material having the lubricating property at the high temperature (6) contains chromium and/or chromium oxide (Cr2O3) and/or hexaboron nitride (hBN). An electrode formed by compression molding of the high-temperature hard material, and the high-temperature lubricating material containing at least one of Cr and hBN and having the lubricating property at the high temperature is used as the electrode for the electro-discharge surface treatment.

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.
