The Influence of Alloying Elements on Surface Hardness of Ferritic Nitrocarburizing Layers of Barrels
Original language description
The article deals with a chemical composition of saturated layers after ferritic nitrocarburizing process. Experiments are focused on using of gas ferritic nitrocarburizing processes for surface treatment due to increasing of surface hardness with low influence on the dimensional accuracy. Ferritic nitrocarburizing processes were applied to steels 42CrMo4 (sample A4) and 32CrMoV12-10 (sample B4) used for weapon manufacturing, which were subsequently evaluated by electron microscopy due to documentation of surface morphology; GDOES and microhardness methods due to check of the fundamental mechanical properties significant for requiring function of barrel. The results of measurement showed high influence of alloying elements on surface hardness of created carbide-nitride layer after chemicalheat treatment process. Main task was to compare microhardness and morphology after ferritic nitrocarburizing in accordance with chemical composition.
