| titleOfInvention | Material for spark plug electrode and method for producing same |
| abstract | The present invention discloses a spark plug electrode material including a substrate formed of Ir or Ir alloy, and an antioxidant film covering a surface of the substrate. Here, an underlying layer formed of Au is formed on a surface of the substrate formed of Ir or Ir alloy, and on the underlying layer, a Ni film having a thickness of 3.0 μm or more and 8.0 μm or less is formed as an antioxidant film. The Ni film turns into an antioxidant film formed of Ni oxide in an oxidizing atmosphere at 500° C. or higher. Owing to the antioxidant film, the spark plug electrode material of the present invention has an excellent high-temperature oxidation property. |
