“…It is also apparent that the non-case-hardened alternative alloys were able to achieve wear performance competitive to the case-hardened 20MnCr5. This has been discussed in detail in previous work [1]. Tribofilm protected sample pairs, however, show very strong reductions in wear, in some cases with coefficients reduced by over 90%.…”

“…Both 36NiCrMoV1-5-7 and 45SiCrMo6 are industrially available materials, as their trade names suggest, and were not case-hardened. Detailed descriptions of the applied heat treatment regimes and elemental analyses, as well as characterization of material microstructures and residual stresses, have been previously provided for all testing materials [1]. All testing was performed on twin disk testing rigs, which are described later under Slip-rolling endurance testing.…”

“…1). Detailed description of these twin disk testing rigs has been provided in previous work by these authors [1]. The applied loads are not merely random assignments, but rather are oriented according to ISO 14635-1, whereby a load stage 12 in the FZG test rig (from the Institute of Machine Elements of the Technical University Munich) is accurately represented by an average contact pressure P 0Mean of approximately 1250 MPa (or as P 0max of 1875 MPa), and is the most intense and relevant testing procedure currently given for gear components [16].…”

“…One possible solution for this problem, aside from the application of wear resistant coatings, is to apply alternative alloys with increased fracture toughness and strength [1]. Such novel alloys allow expensive and energy-intensive thermochemical treatments to be circumvented, and still achieve respectable wear performance.…”

The chemical composition of the steel is one of the primary characteristics that influence the mechanical properties of high-stressed machine parts such as barrels of small arms weapon. Heat treatment is the most important technology to reach requested mechanical properties. By a suitable combination of mechanical and tribological properties, it is possible to improve the surface of highly stressed parts as to improve the wear resistance of barrel surface. Thus, surface technology is next step for obtaining new properties as tribological properties or preferable mechanical properties. Due to obtain suitable microstructure and wear resistance the samples of C35, 34Cr4, 37Cr4 and 42CrMo4 were heat-treated with following chemical heat treatment by gas nitriding process, for 6 hours. This paper deals with the influence of alloying elements of structural steels on surface microhardness and depth of diffusion layer. The gas nitriding process caused the creation of a compound layer on the surface of the steel. This layer leads to significant improvement in wear resistance. The concentration of alloying elements was analysed by OES methods. The technology of nitriding was applied to annealed, tempered and quenched steels. After chemical heat treatment, new surface morphology was created. The surface layers of the samples were analysed by microhardness method; surface morphology was evaluated by SEM method. Experimental part concerns structural steels with a concentration of alloying elements to 1 wt.%. In experimental part, the influence of alloying elements on the diffusion process in Fe-C system and the microhardness of the surface was proved.K e y w o r d s : gas nitriding, microhardness, chemical composition, diffusion, barrel
