The disclosure relates to a housing for a spark plug, having a bore along the longitudinal axis X of the housing, the housing comprises an outer side and an inner side and a galvanically applied nickel and zinc-containing protective layer is arranged on at least one part of the outer side of the housing. A sealing layer, which contains silicon, is arranged on the nickel and zinc-containing protective layer.

Spark plug housing having a galvanic nickel and zinc-containing protective layer and a silicon-containing sealing layer, spark plug having said housing, and method for producing said housing

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 housing for a spark plug. The housing includes a bore along the longitudinal axis X of the housing, as the result of which the housing has an outer side and an inner side, and an electroplated or chemically applied nickel-containing protective layer situated on at least one portion of the outer side of the housing and a sealing layer situated on the nickel-containing protective layer. The sealing layer contains silicon. A first intermediate layer is applied between the housing and the nickel-containing protective layer and/or a second intermediate layer is applied between the nickel-containing protective layer and the sealing layer and/or a cover layer is applied on the sealing layer. The sealing layer may be free of chromium.
