Production method of spark plug designed to provide high temperature oxidation resistance and weld strength and spark plug produced thereby |
摘要 |
A spark plug and a production method thereof is provided which is designed to improve the high temperature oxidation resistance of a ground electrode without sacrificing the mechanical strength of a weld of the ground electrode with a metal shell. The ground electrode is made of a Ni-based alloy containing 10% or more by weight of Cr and 1.5% or more by weight of Al and joined to the metal shell by resistance welding in a substantially oxygen free atmosphere.
