Sažetak
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.
