Experimental Study on Nitriding of Sm-Fe Melt AITranslate
Abstract AITranslate
The static nitriding and bottom-blown nitrogen nitriding processes of Sm-Fe melt were re- searched. The phase, morphology and composition of nitrided alloy samples were investigated through XRD,SEM and EDS, respectively. And the effects of the two nitriding processes were compared. The results show that during static nitriding of Sm-Fe alloy melt,the surface of the sample is easy to form highmelting-point refractory Sin2O3. Sm2O3 covers Sm-Fe alloy surface to hinder the diffusion of N atoms into the melt,and therefore the static nitriding method fails to achieve the desired nitriding effect. The nitrogen element is found in Sm2Fe17 phase of the alloy sample after bottom-blown nitrogen nitriding,and the main peak of Sm2Fe17 phase shifts to a smaller angle,indicating that N atoms enter Sm2Fe17 phase and the nitriding effect is good.
