	The paper reviews the process of surface layer development with the use of carbonitriding and carbonitriding with oxidation. Employed for that purpose was a modern and ecological method called ZeroFlow. Research was carried out using HS 6-5-2 steel. Single-component nitrifying atmosphere of ammonia NH3 was applied. The temperature of the processes was 570 °C. Diffusion layers were obtained on the steel. The thickness of the layers achieved during the microstructural research equalled from about 125 μm after carbonitriding with oxidation to about 187 μm after carbonitriding. Surface hardness HV1 was the highest for the carbonitrided layer - 1027 HV1, whereas in the case of carbonitriding with oxidation it amounted to 1018 HV1. As far as surface hardness HV30 is concerned, it was at the level of 813 HV30 for the carbonitrided layer and 795 HV30 for carbonitriding with oxidation. Surface hardness test results indicate surface layer hardening.
