Abstract (en)
Method for production of a hardened profile part from a hardenable steel alloy having cathodic corrosion protection by: (a) application of a Zn coating to a hardenable steel alloy sheet; (b) roll profiling of the coated sheet with shaping into a roll-shaped profile strand; (c) heating of the coated steel sheet to the hardening temperature with admission of atmospheric oxygen, formation of a superficial oxide skin from oxygen-affine elements; and (d) cooling. Independent claims are included for: (1) a corrosion protection Zn layer for a steel sheet; (2) a hardened and profiled component in hardenable steel with a cathodically protected layer obtained as above.
