ABSTRACT
The structure and chemical composition of composite multicomponent oxynitrided layers obtained in multiplex processes that combines electrochemical chromium deposition on AISI 1045 steel and glow discharge assisted oxynitriding are described. Quantitative X-ray microanalysis shows that the layers of type: Cr2O3 + CrN + Cr2O3 + Cr2N + Cr + (CrXFeI-x)2N + (Cr,Fe)7C3 formed. These layers have a diffusion character and show a good adhesion to the substrate. They show very high corrosion resistance, markedly greater than that of chromium coated and only nitrided steel.

tlenoazotowanie jarzeniowe, warstwy kompozytowe, odporność korozyjna
Przedstawiono wyniki badań mikrostruktury i składu chemicznego wieloskładnikowych kompozytowych warstw wytworzonych w procesie tlenoazotowania w wyładowaniu jarzeniowym na stali AISI 1045 pokrytej elektrolitycznie warstwą chromu. Mikroanaliza rentgenowska wykazała powstawanie warstw typu ; Cr2O3 + CrN + Cr2O3 + Cr2N + Cr + (CrXFeI-x)2N + (Cr,Fe)7C3. Warstwy te mają dyfuzyjny charakter, dobrą przyczepność do podłoża i b. wysoką odporność korozyjną.
