Definitions

  • the invention relates to a method for nitriding or nitrocarburizing workpieces made of alloyed steels, in particular corrosion-resistant steels with greater than 13% by weight chromium, in a gaseous, preferably ammonia-containing nitrating or nitrocarburizing atmosphere, in which the workpieces are previously subjected to a pretreatment.
