abstract = "When performing nitriding of stainless steels, there is a decrease
or even complete depletion of chromium in the nitrogen rich region
just beneath the surface, inhibiting the formation of passivated
Cr oxide layer, beneficial to withstand corrosive attacks and
Cr/Fe nitrides, responsible for hardness enhancement. To overcome
this problem, a hybrid technique was used, consisting of
depositing a thin chromium film on steel surface and then
bombarding it with nitrogen ions. By a complex recoil process,
chromium atoms are implanted into the steel matrix. Plasma
immersion ion implantation (PIII) was used in this bombardment.
The new Cr-rich layer allows the formation of Cr oxides and
nitrides. Treated surfaces were characterized by Auger electron
spectroscopy (AES) and conversion electron Mossbauer spectroscopy
(CEMS), showing formation of a new Cr-rich layer.",
