Evaluation Hard Layers in Steel AISI 8620

Abstract:

In the present study, identify the fracture toughness and strength adhesion of borided layers in Steel AISI 8620 by boriding dehydrated paste. The formation of the borided at a temperature range of 1173, 1223 and 1273 K for 4, 6 and 8 h. X-ray diffraction analysis revealed peak of FeB, Fe2B, MoB and CrB and The distribution of alloying elements was detected by means of energy dispersive Spectroscopy (EDS), the Fracture toughness of the layers is estimated at 15 and 30 um from surface using different loads indentation Vickers, using Palmqvist crack model, the adherence of the layer/substrate was evaluate in qualitative form though the Rockwell C. The fracture toughness of the borides depends strongly on temperature and time boriding. Also, good adhesion is obtained around the Rockwell C indentation prints on the borided layer-substrate-interface.
