摘要:
Components which are subject to operating loads can often be passed for refurbishment by means of an acid treatment. The time for which the components remain in the acid has hitherto been determined empirically, which means that individual loads are not taken into account. The process according to the invention for the surface treatment of a component proposes that at least repeatedly a measurement voltage be applied to the component, resulting in the flow of a current, the time profile of which represents the state of the surface treatment and is used to decide upon when to terminate or interrupt the acid treatment.
