  • Method for coating sliding surface of high-temperature member, high-temperature member and electrode for electro-discharge surface treatment
    Patent number: 9284647
    Abstract: 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.

  • ROTATING MEMBER AND METHOD FOR COATING THE SAME
    Publication number: 20100124490
    Abstract: A pulsed discharge is generated between tip ends of a rotating member such as a blade and a discharge electrode including a hard material such as cBN in dielectric liquid or gas by a power supply for discharge to melt the discharge electrode, and a part of the discharge electrode is attached to the tip end of the rotating member to form an abrasive coating film including the hard materials such as cBN.
