Abstract

Goal of this contribution was study of possibilities functional graded structure (FGS) fabrication and 3D parts on their base via layer - by - layered Selective Laser Sintering (SLS) method from nitinol powder (intermetallics phase - NiTi) and/or titanium. Particularities a micro and macro structures, formed under such regimes of syntheses, were determined. The morphological and element analyses were performed by SEM and energy dispersive X-ray spectroscopy. The interlayer surface roughness was investigated using an optical microscope. It was shown that FGS delamination had been revealed in the NiTi + Ti system, while homogeneity between of layers was in the system - titanium, chemical cladding by the nickel (NiTi2 - phase) + Ti.
