10. A coating installation, comprising:
at least one coating device for coating a component, including:
a housing having an outer anode that is configured to receive the component;
an inner anode that can be introduced into a through-opening of the component; and
a voltage-generating device configured to generate a first voltage between the outer anode and the component, and a second voltage between the inner anode and the component;
wherein the housing has an inlet for introducing a process medium into the housing, and an outlet for discharging the process medium from the housing,
wherein the housing includes a cover having a clamping device, the clamping device being configured to clamp the component to hold the component in a predefined position inside the outer anode,
wherein the component is a spark plug housing having a ground electrode, and the clamping device being configured to clamp the ground electrode,
wherein the clamping device at least partly covers a surface of the ground electrode in a clamped state, and the clamping device covering at least 80% of the surface of the ground electrode in the clamped state.
