Characterization of Borided DIN X165CrMoV12 Steel
Öz
In the present study, characterization properties of borides formed on DIN X165CrMoV12 steel have been investigated. Boriding was performed in a solid medium consisting of Ekabor-II powders at 1073 and 1273K for 4 h. The boride layer was characterized by optical microscopy, X-ray diffraction technique and the micro-Vickers hardness tester. X-ray diffraction analysis of boride layers on the surface of the steels revealed the existence of FexBy and CrxBy compounds. Depending on the chemical composition of substrates, the boride layer thickness on the surface of the DIN X165CrMoV12 steel was found to be 32.75 μm and 78.92 μm at 1073 and 1173K for 4 h, respectively. The hardness of the boride compounds formed on the surface of the DIN X165CrMoV12 steel ranged from 1638 to 1892 HV0,1, whereas Vickers hardness values of the untreated steel DIN X165CrMoV12 was 432 HV0,1.
