    • The invention relates to a method for the production and removal of a temporary protective layer for a cathodic coating, particularly for the production of a hardened steel component with an easily paintable surface, wherein a steel sheet made of a hardenable steel alloy is subjected to a preoxidation, wherein said preoxidation forms a FeO layer with a thickness of 100 nm to 1,000 nm and subsequently a melt dip coating is conducted, wherein, during the melt dip coating, a zinc layer is applied having a thickness of 5 to 20 μm, preferably 7 to 14 μm, on each side, wherein the melt dip process and the aluminum content of the zinc bath is adjusted such that, during the melt dip coating, an aluminum content for the barrier layer results of 0.15 g/m2 to 0.8 g/m2 and the steel sheet or sheet components made therefrom is subsequently heated to a temperature above the austenitizing temperature and is then cooled at a speed greater than the critical hardening speed in order to cause hardening, wherein oxygen-affine elements are contained in the zinc bath for the melt dip coating in a concentration of 0.10 wt.-% to 15 wt.-% that, during the austenitizing on the surface of the cathodic protective layer, form a thin skin comprised of the oxide of the oxygen-affine elements and said oxide layer is blasted after hardening by irradiation of the sheet component with dry ice particles.
    • 本发明涉及一种生产和除去阴极涂层的临时保护层的方法,特别是用于生产具有容易涂漆的表面的硬化钢部件,其中由可硬化的钢合金制成的钢板经受 预氧化,其中所述预氧化形成厚度为100nm至1000nm的FeO层,随后进行熔融浸涂,其中在熔融浸涂期间,施加厚度为5至20μm的锌层,优选 在每一侧上为7至14μm,其中熔融浸渍工艺和锌浴的铝含量被调节,使得在熔融浸涂期间,阻挡层的铝含量为0.15g / m 2至0.8g / m2,然后将由此制成的钢板或片材组件加热到高于奥氏体化温度的温度,然后以大于临界硬化速度的速度冷却以引起硬化 ,其中在用于熔融浸涂的锌浴中含有氧亲和元素,其浓度为0.10重量%至15重量%,在阴极保护层表面的奥氏体化期间形成薄的皮肤 由氧化仿生元素的氧化物构成,并且所述氧化物层通过用干冰颗粒照射片材组分而硬化后喷丸。
