Definitions

  • the present invention relates to a steel sheet provided with a sacrificial cathodic protection coating, more particularly intended for the manufacture of automotive parts, without being limited thereby.
  • the other family of metal coatings commonly used for the production of automobile parts is the family of aluminum and silicon-based coatings. These coatings do not generate microcracking in the steel when deformed due to the presence of an Al-Si-Fe intermetallic layer and have good paintability. Although they provide barrier protection and are weldable, they do not provide cathodic protection.
  • the present invention therefore aims to overcome the disadvantages of the coatings of the prior art by providing coated steel sheets having a reinforced protection against corrosion, before and after implementation by stamping, in particular.
