Abstract
A press-hardened steel component and a method of producing the same. In one form, a workpiece that will be formed into the component includes a coating that is pre-diffused with metal from the workpiece substrate. Examples of such protective coatings may include aluminum-based coatings, as well as from aluminum and silicon combinations. The pre-diffusion of the workpiece permits it to be subjected to the high heating rate of a subsequent press hardening operation without causing localized melting or vaporization of the protective coating.
