Abstract

본 발명은 하나, 둘 또는 모든 전극의 적어도 작동부가 1400°C이상의 용융점을 작고 적절한 인성, 내열충격성 및 전기 전도성을 갖도록 선택된 금속간 화합물을 포함하는 금속으로 제조된 스파크 플러그 또는 다른 스파크 점화기에 관한 것이다. 금속간 화합물은 다상의 금속의 하나의 상으로 형성될 수도 있다. 루테늄 알루미나이드는 양호간 금속간 화합물로 개시하였다.The present invention relates to spark plugs or other spark igniters made of metal comprising an intermetallic compound selected such that at least the operating portion of one, two or all electrodes has a melting point of at least 1400 ° C. and has adequate toughness, thermal shock resistance and electrical conductivity. . The intermetallic compound may be formed with one phase of a multiphase metal. Ruthenium aluminide has been described as a good intermetallic compound.
