Abstract (en)
[origin: ES8401531A1] Low cyanide nitriding salt baths which are composed of alkali cyanate and alkali carbonate and used for treating components made of steel and iron produce coatings on the surface of the component in some cases and can lead to problems in the use of the components. A satisfactory surface quality can be obtained from nitriding salt baths which additionally contain 0.5 to 100 ppm of selenium.
