Method for testing corrosion behavior of bodywork of motor car in test stand, involves charging component with current in wet condition by power supply so that current flow is caused through joint between individual components

摘要

The method involves thermally and/or mechanically loading a component (1) by temperature changes. The component is dipped in an aqueous electrolyte (6) e.g. salt solution, for a preset time. The electrolyte is provided in a bath (5) such that bath parameters are controlled. The component is removed from the electrolyte. The component is charged with current (I) in a wet condition by a power supply (7) so that a current flow is caused through a joint (4) between individual components (2, 3) of the component. A voltage (U) between the individual elements is measured.
