Abstract: In relation to salt bath ferritic nitrocarburizing, a new surface modification
technology, such problems as technological processes and their control, determination of nitrocarburizing temperature and duration and other parameters, control of CNO and CN contents in the salt bath, maintenance of the salt bath, conditioning heat treatment for workpieces and examination of nitrocarburizing quality, were all-sidedly described. In addition, the salt bath ferritic nitrocarburizing was explained in association with actual production.
