Investigation of Characterization of Borided AISI D3 Steel

Abstract

In the present study, characterization properties of borides formed on AISI D3 steel have been investigated. 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 FeB, Fe2B, CrB and Cr2B compounds. Depending on the chemical composition of substrates
and boriding time, the boride layer thickness on the surface of the steel ranged from 32.15 μm and 73.68 μm. The hardness of the boride compounds
formed on the surface of the steels ranged from 1692 to 1874 HV0,1, whereas Vickers hardness values of the untreated the steels was 584 HV0,1.
