Properties of Powders from Stainless and Heat Resistant Alloys Produced by Gas Dynamic Spray for Manufacturing Parts of Complex Shape

Abstract:

The objects of the study were powders of stainless steel and superalloy obtained gas-dynamic spray in the VIGA 2B (ALD, Germany). It have been investigated the microstructure, structural and phase composition, grain size, physical, chemical and technological properties of powders of alloys obtained by gas-dynamic spray melts.To study the structure and properties of powders of different factions were the used electron microscopy techniques, metallographic, sedimentation, X-ray, energy dispersive analysis, imaging, chemical, and other analytical methods. The powders have a spherical shape, low impurity content, good fluidity and can be used for producing parts by selective laser sintering, slip casting, injection molding, coating plasma and the sintering.
