The present invention relates to a process for producing corrosion resistant and wear resistant layers on materials that are based on iron, in which the areas that are close to the surface are enriched with nitrogen, carbon, and oxygen. In order to produce an iron-based material with a particularly durable and effective corrosion and wear resistant layer, it is proposed that, in a first step of the process, the material is subjected to nitrocarburation in order to form a connective layer consisting of iron carbonitrides. The material is then subjected to a plasma-assisted low-pressure process to activate the surface of the material that has the connective layer, before an unbroken and even oxide layer is formed on the existing connective layer during subsequent oxidation. Corrosion and wear resistant layers with service lives clearly superior to known protective layers in standardized corrosion tests are obtained by the activation of the connective layer formed in the nitrocarburation process during the plasma-assisted low-pressure process.
