Abstract
Abstract In a device and a method for passivating components, a thixotropic gel is arranged in the shape of a ring around a component. The inside space surrounded by the thixotropic gel is filled with a passivating gel until the component is completely covered with passivating gel. The gels are subsequently hardened.
