Treating joint connection points of a motor vehicle that are disposed in endangered areas of two components for electrochemical corrosion, comprises introducing a corrosion protection agent in an intermediate gap between the two components

摘要

The method comprises introducing a corrosion protection agent (20) in an intermediate gap between the two components (10, 12), where the introduction takes place in the joint connection points (14) by an impact of an ultrasound. One of the components is impacted using the ultrasound to introduce the corrosion protection agent. The corrosion protection agent is passivating agent, oil, wax, and adhesive or elastomer. The ultrasound is coupled into the component using ultrasound head (22). A coupling medium (24) e.g. solvent and ethanol is used for coupling the ultrasound into the component.
