Abstract

POSTUPAK ZA NITRIRANJE POD PRITISKOM RADNIH KOMADA OD ČELIKA u gasnoj atmosferi koja sadrži atomski azot, na temperaturama iznad 425В°C i pritiscima iznad 0,2 megapaskala, naznačen time, što se gasna atmosfera sastoji od 5 do 95 zapr.% amonijaka i 95 do 5 zapr.% molekularnog azota i što se nitriranje vrši pri konstantnom pritisku.
