摘要： A process for hardening a work piece of stainless steel through diffusion of the elements carbon and/or nitrogen into the work piece surfaces. The work piece is submerged into a molten salt bath and subjected to the molten salt bath for a period ranging from 15 minutes to 240 hours at temperatures below 450° C. In addition to potassium chloride and lithium chloride, the molten salt bath contains an activator substance consisting of barium chloride, strontium chloride, magnesium chloride and/or calcium chloride, and a free or complex cyanide as carbon-donating substance.

摘要： The invention relates to a method for producing corrosion-resistant surfaces of nitrated or nitrocarburated steel components, the surfaces having roughness heights (Rz) of Rz≧1.5 μm. The method comprises the following steps: oxidation of the surfaces of the nitrated or nitrocarburated components in a first oxidation step; carrying out at least a second oxidation of the component surfaces in an immediately subsequent oxidation step; polishing the component surface in a final method step, directly after the final oxidation.

摘要： It is known to regenerate salt baths for nitriding parts of iron and steel with polymers of organic materials, which polymers, however, could not be used in carburizing salt baths since with them there only are formed slight amounts of carburizing active cyanide, the baths foam, and carbon residues are formed. An excellent regeneration agent for carburizing salt baths is obtained by using polymeric organic compounds of the overall composition [C.sub.6 H.sub.x N.sub.y ].sub.z where x is 3 to 5, y is 5 to 8, and z is 10 to 10,000. These compounds are obtained by reacting formaldehyde with cyanamide and/or dicyandiamide and/or melamine and pyrolytically decomposing the reaction product at 300.degree. to 600.degree. C.
