	The paper presents the results of physical and mechanical properties of steel HS6-5-2 after nitriding, carbonitriding and carbonitriding with oxidation process. Modern and ecological method Zero Flow was used. Applied mononitriding atmosphere of ammonia NH3. The temperature of the processes up to 570°C. After nitriding surface of the phase, surface hardness, hardness distribution in depth and the microstructure were tested. As a result of nitriding, carbonitriding and carbonitriding with oxidation process achieved diffusion layers on steel HS6-5-2. A thickness ranged from 0.147mm for carbonitriding with oxidation layer to 0.325 mm for nitriding layer. The results of surface hardness show hardening of the surface layer. The main phases detected in the studied materials are Fe3N, Fe4N and Fe3O4. Nitriding and carbonitriding processes lead almost to the same results in contrast to the carbonitriding with oxidation process which causes presence of greater amount of the Fe3O4 phase
