Fatigue Fracture Roughness Character After Plasma Nitriding Process
Original language description
In this study, the cyclic loading of steel samples 41CrAlMo7-10 (1.8509) were made. This steel is suitable for plasma nitriding proces. The experiment included 4 different plasma nitriding procedures. The differences were applied in plasma nitriding atmosphere and procedure duration. Then follow-up a fatigue test. The fatigue tests were carried out in accordance with the CSN 42 0363 Fatigue Testing of Metals, Methodology of Testing in the machine R.R.Moore L2568 of Instron Co. Fatigue tests were compiled graphically and numerically using Wöhler`s (S-N) curve in a semi-logarithmic form. The testing was stopped after reach the fracture of tested sample or after 107 cycles. Area of study was fatigue fracture. Specifically, part of fatigue fracture around inclusions and their vicinity. This part is known as fish-eye and has specific shape and morphology in terms of surface topography. The surface topography of fatigue cracks were evaluated on Talysurf CCI. Roughness parameters were tested in this area at six defined lines from fatigue crack initiation.
