Summary: | Since a coating film composed of an oxide such as Fe3O4 or FeO and Fe (metal) is formed on the surface of a base material by electric arc spraying of an iron wire principally comprising Fe, a piercing plug can attain excellent heat shielding properties and seizure prevention properties due to this coating film, and the plug can have a long life. When the plug is regenerated, a coating the film can be formed again by sequentially performing shot blasting and arc spraying on a just-pierced plug, and thus the plug can be regenerated in a short time at a low cost. |
