Abstract (en)
[origin: US5102476A] Components made from steel can be nitrocarburized in cyanate- and cyanide-containing salt baths within relatively short times if the process is carried out at 600 DEG to 700 DEG C. in a first stage and at 560 DEG to 590 DEG C. in a second stage. The components exhibit the same or better characteristics as compared to considerably longer processing at 560 DEG to 590 DEG C.
