A spark plug housing. The spark plug housing includes an inner side, an outer side, and a longitudinal axis, which extends from an end of the spark plug housing facing toward the combustion chamber up to an end of the spark plug housing facing away from the combustion chamber. The spark plug housing includes a circumferential shoulder on its inner side, which is designed so that a spark plug insulator rests thereon, and a corrosion protection layer on its inner side, which is formed on a section of the inner side of the spark plug housing, the section extending from the end of the spark plug housing facing toward the combustion chamber to at least over the shoulder and along the inner circumference of the spark plug housing.

Spark plug housing including corrosion protection on the inner side and spark plug and manufacturing method

A spark plug having a housing, an insulator disposed in the housing, a center electrode situated in the insulator, a ground electrode disposed on the housing, and at least one sealing element, the at least one sealing element being situated on the housing, in particular between the insulator and the housing, wherein the at least one sealing element is made from an at least ternary alloy, and the alloy contains copper as the main constituent.
