摘要： A spark plug and method of construction thereof is provided. The spark plug includes a metal shell having a through cavity, a lower insulator and a plastic upper insulator. The lower insulator is received in the through cavity and has a through passage with a center electrode received therein. A ground electrode is operatively attached to the shell in spaced relation from the ground electrode to provide a spark gap. The plastic upper insulator has a distal end received in the through cavity of the shell and a terminal end extending axially outwardly from the shell. The upper insulator has a through passage extending between the terminal end and the distal end. An elongate conductive member is received in the through passage of the upper insulator and is configured for electrical communication with the center electrode.

摘要： A spark plug having one or more electrodes at least partially fabricated from an aluminum-containing Ni-based alloy. The alloy is a volume -stable alloy that includes a Ni3A1 precipitate in a ?' -phase distributed in a Ni matrix ?-phase. The precipitate is formed in the alloy prior to the alloy being used to fabricate electrodes and thus prevents additional Ni3Al precipitate from being formed in the alloy once in service in a high-temperature environment. This, in turn, prevents a volume decrease of the alloy that may lead to an increased spark gap and spark plug malfunction. The volume-stable alloy may be made by solution treatment, quenching, and heat aging of a Ni-Cr-Al-Fe alloy.
摘要翻译：具有至少部分地由含铝的Ni基合金制成的一个或多个电极的火花塞。该合金是体积稳定的合金，其包括在α' 相分布在Ni基体α相中。在用于制造电极的合金之前，在合金中形成沉淀物，从而防止在合金中在高温环境中使用中另外的Ni 3 Al沉淀物形成。这又防止合金的体积减小，这可能导致火花间隙增加和火花塞故障。体积稳定的合金可以通过Ni-Cr-Al-Fe合金的固溶处理，淬火和热老化制成。
