20.500.12556/RUL-159822 Degradation processes of two compound layers on nitrided surfaces during the wear test by ‘‘block on hot Al cylinder’’ The results obtained in the study help to explain the degradation process of the nitrided steel compound layer. Compound layers with different properties on gas-nitrided H10 tool steel blocks were tested for wear with ‘‘block on hot Al cylinder’’. Degradation processes were observed on both compound layers with different properties and at three contact pressures. In order to observe the degradation processes in the compound layers, the wear tests were interrupted at various fixed time intervals and the resulting changes were closely monitored. The comprehensive analysis highlighted the complexity of the degradation process in the compound layers and emphasized the existence of complex relationships between the above-mentioned parameters. The reaction of the nitrided steel surface with hot Al is more pronounced in areas with lower contact pressure, while adhesive removal and furrow formation are pronounced in areas with low and medium contact pressure. This process begins with a sufficient density of the areas where islands of adhesive removal are located, their enlargement during the test, the breaking up of the walls between them, and finally the removal of the compound layer in the sliding direction, which appears as furrowing in the final phase of wear. wear nitrided steel hot-work tool steel thermal fatigue aluminium extrusion tool surface degradation obraba nitrirano jeklo orodno jeklo za delo v vročem toplotno utrujanje ekstruzija aluminija obraba površine orodja true false true Angleški jezik Slovenski jezik Članek v reviji 2024-07-26 09:38:56 2024-07-26 09:38:57 2024-07-27 04:03:58 0000-00-00 00:00:00 2024 0 0 Str. 4006–4027 no. 8 Vol. 76 2024 0000-00-00 Zaloznikova Objavljeno NiDoloceno 0000-00-00 0000-00-00 0000-00-00 669 1047-4838 10.1007/s11837-024-06693-1 200251907 s11837-024-06693-1.pdf s11837-024-06693-1.pdf 1 FD95CEF70F410F96C703125379A78F16 2a73ee32ed3572956def5fc53fcb72d401444bde0bf7e35276006cbb99037a70 6eb060d1-4b22-11ef-8f74-0050569b8976 https://repozitorij.uni-lj.si/Dokument.php?lang=slv&id=188049 https://link.springer.com/article/10.1007/s11837-024-06693-1 0 2a34c7e6-4b22-11ef-8f74-0050569b8976 https://repozitorij.uni-lj.si/Dokument.php?lang=slv&id=188048 Naravoslovnotehniška fakulteta 0 0 0
