Abstract
U radu je istraživan utjecaj parametara visokotemperaturnog karbonitriranja na otpornost adhezijskom trošenju čelika 18CrNi8. Karbonitriranje čelika provedeno je u plinskoj atmosferi na temperaturi 920 °C, a varirani su C i N potencijal tijekom procesa. Ispitivanje trošenju obavljeno je metodom disk/disk uz variranje brzine relativnog gibanja uzorak/kontra tijelo (UZ/KT) i variranje veličine sile opterećenja na ispitne uzorke. Na temelju analize rezultata gubitka mase ispitnih uzoraka konstatirano je da su postupkom visokotemperaturnog karbonitriranja 1 (VTKN-1) postignute tvrdoće oko 20 % više nego postupkom visokotemperaturnog karbinitriranja 2 (VTKN-2). Iz rezultata ispitivanja otpornosti trošenju pri adhezijskom trošenju metodom disk/disk, uzorak (UZ) čelika 18CrNi8, kontra tijelo (KT) 42CrMo4, oba visokotemperaturno karbonitrirana, može se uočiti da uzorci obrađeni u uvjetima visokotemperaturnog karbonitriranja (VTKN-1) imaju manji gubitak mase u odnosu na uzorke obrađene postupkom visokotemperaturnog karbonitriranja 2 (VTKN-2). Utjecaj veličine opterećenja (sile) uzorak/kontra tijelo (UZ/KT) je naročito izražen pri većim brzina relativnog gibanja.
Abstract (english)
In this paper the influence of high temperature carbonitriding parameters on the adhesion wear resistance of steel 18CrNi8 was investigated. Carbonitriding of steel 18CrNi8 was performed in the gas atmosphere at a temperature of 920 °C, and potentials of C and N during process are varied. Testing of adhesion wear was performed with method disc/disc by varying the speed of relative motion of sample/counter body and varying the size of force load on the test samples. Based on the analysis results of the mass loss of test samples it was concluded that by the process of high temperature carbonitriding 1 are achieved hardness about 20 % more than by the process of high temperature carbonitriding 2. From the results of resistance test to the adhesion wear by method disc/disc, sample of steel 18CrNi8, counter body of steel 42CrMo4, both high temperature carbonitriding, it can be seen that the samples processed under conditions of high temperature carbonitriding 1 have a lower mass loss relative to the samples processed under conditions of high temperature carbonitriding 2. The influence of size load (force) sample/counter body is particulary pronounced at the higher speed of relative motion.
