Improvement of surface layer properties of some constructional steels induced by applying thermodiffusional duplex treatment

The contribution deals with the preliminary results obtained in investigation concerning application of the duplex treatment to the low-carbon and low-alloyed steel samples (C45E, C15E, 42CrMo4 and 20MnCr5). The duplex treatment included boronising (at 900°C for 4 h in Ekabor 3 powder)and subsequent plasma nitriding processes (at 520°C for 40 minutes, 30 vol% nitrogen and 70 vol.% hydrogen, using PN-Mono 5 unit). In this study, the case and core properties of treated steels have been investigated experimentally by using: optical microscopy and SEM observations, X-ray diffraction analysis and measurements of microhardness profile on the cross-section of the treated steel samples. The results obtained by the above techniques are mutually consistent, and they are in agreement with the findings obtained by other researchers.
