Abstract
In a method for producing corrosion and wear resistant coatings on iron material, in which subsurface areas are enriched with nitrogen, carbon, and oxygen, the iron material is nitrocarburized for forming a connective coating of carbonitride. The surface of the iron material is activated with a plasma-supported vacuum process. The ion material is subsequently oxidized to form a continuous oxide coating.
