Material and technological investigation of machined surfaces of the OCHN3MFA steel

Abstract: This paper deals with the effect of selected cutting parameter values in machining of OCHN3MFA steel on AFM and SEM microstructural analysis, cutting forces, nanohardness, 2D and 3D surface roughness, and material removal rate of surface layers after machining. OCHN3MFA steel was selected and used to perform experiments. Firstly, the selected steel was investigated before machining tests, due to the checking of the initial microstructure and chemical composition. The microstructure was performed on the Tescan … Show more

“…For all performed indentation standard trapezoid load curve with the maximum test load F = 2000 µN and t = 2 s holding period is used. These parameters have been proven in previous research focused on high strength 33NiCrMoV15 steel [11].…”

“…The results are presented in the form of CCT diagram, which can be useful in designing of the temperature cycles for the production and processing of high performance tool steel X155CrV-Mo12. The higher percentage of chromium in the mate- rial results in the formation of Cr 7 C 3 carbide, which results in an increased value of the hardness of the material [9,10]. Provided the martensitic transformation is achieved, the resulting critical cooling rate is set at 5 °C/s.…”

“…Tungsten carbide (WC) is often used as a thin coating, characterized by high values of hardness (42 GPa [1][2][3]), wear resistance, as well as a low coefficient of friction (COF, 0.22 [1,2]), whereas the surface hardness of unmodified steel is 5 GPa [4]. Therefore, WC is often applied for the protection of functional surfaces of machining components made of steel, and for coating high-speed steel.…”
