Abstract
A pretreatment method for pretreating components, which are each formed of at least two different materials, prior to a coating process. The pretreatment method includes the steps: alkaline degreasing; chemical pickling in a first pickling medium; anodic pickling in a second pickling medium; and cathodic degreasing.

A pretreatment method for pretreating a component, which is formed of at least two different materials, the method comprising the following steps:
- alkaline degreasing the component;
- chemical pickling the component in a first pickling medium;
- anodic pickling the component in a second pickling medium;
- and
- cathodic degreasing the component.
A coating method for coating a component which is formed of at least two different materials, the method comprising the following steps:
- pretreating the component using a pretreatment method including:
- alkaline degreasing the component,
- chemical pickling the component in a first pickling medium,
- anodic pickling the component in a second pickling medium, and
- cathodic degreasing the component;
- and
- generating a coating of the component using a nickel electrolyte.
A spark plug housing formed of at least two different materials, the spark plug housing being coated by:
- pretreating the spark plug housing using a pretreatment method including:
- alkaline degreasing the spark plug housing,
- chemical pickling the spark plug housing in a first pickling medium,
- anodic pickling the spark plug housing in a second pickling medium, and
- cathodic degreasing the spark plug housing;
- and
- generating a coating of the spark plug housing using a nickel electrolyte.
