A method for treating a metal element for an automobile includes hardening the metal element so as to obtain a press hardened metal element. Scale from the press hardened metal element are removed by placing the press hardened metal element in an ultrasonic liquid and preforming an ultrasonic process thereon so as to obtain a de-scaled press hardened metal element. The ultrasonic liquid is an aqueous solution comprising an organic carboxylic acid in a concentration of from 0.1 to 10 vol.-%. The de-scaled press hardened metal element is coated in a coating process with an anti-corrosion coating.

Method of treating a metal element for an automobile

Method for manufacturing a zinc-coated nonferrous metal component for the production of a corrosion-protected vehicle body in a mixed construction includes providing an untreated nonferrous metal component and applying a coating by zinc diffusion onto the nonferrous metal component. A zinc dust mixture is diffused at a temperature of from 300 to 600&#xb0; C. so as to form a zinc diffusion layer.

Vehicle body components with a metal hybrid construction and production methods for such vehicle body components

A press-hardened component and a method for producing press-hardened components, in particular a bodywork component, from a semi-finished product made from unhardened, hot-formable steel sheet. Various process steps are carried out in the process. A component blank is formed from the semi-finished product by a cold-forming process, in particular a drawing process. The component blank is trimmed at the margin side to a margin contour which approximately corresponds to the component to be produced. The trimmed component blank is heated and press-hardened in a hot-forming tool, and then the press-hardened component blank is covered with a corrosion-prevention layer in a coating step.

Press-hardened component and process for producing a press-hardened component

A method for the production of press-hardened components, in particular a vehicle body component, from a semifinished product () made of unhardened, hot-workable steel sheet. A component blank () is formed from the semifinished product (), pre-coated with a first coating (), by a cold-forming method, in particular a drawing method. The component blank () is trimmed at the margins to a marginal contour (') approximately corresponding to the component () to be produced. The trimmed component blank () is heated and press-hardened in a hot-forming tool (); then the press-hardened component blank () is covered with a second, anticorrosion coating () in a coating step.
