Abstract

Intermetallide phase formation was studied in a powdered Fe–Al system under layer by layer laser cladding with the aim of fabricating the gradient of properties by means of changing the Fe–Al concentration ratio in the powder mixture from layer to layer. The relationships between the laser cladding parameters and the intermetallic phase structures in the consecutively cladded layers were determined. In order to study the structure formation an optical microscopy, X-ray diffraction analysis, measurement of microhardness, scanning electron microscopy (SEM) with energy dispersive X-ray (EDX) spectroscopy analysis were used after the laser synthesis of intermetallic compounds.
Keywords: 3D laser cladding; laser control intermetalic synthesis; functional graded structures (FGS); Fe–Al intermetallide 3D laser cladding; laser control intermetalic synthesis; functional graded structures (FGS); Fe–Al intermetallide
