Originální abstrakt

The purpose of the study is to identify possible changes in different elementary powders (Al, Ti, Co, Cr, Ni, Fe) after being compacted by cold spray kinetic deposition. A deep analysis on the microstructure of the materials prior and after the deposition was performed through Scanning Electron Microscopy, Energy-Dispersive X-Ray Spectroscopy, Electron Channeling Contrast, X-ray Diffraction, Differential Scanning Calorimetry and microhardness tests. The results indicate that there are noticeable alterations in the microstructure of the materials due to plastic deformation processes which occur during the cold spray deposition, within the material presented up to 58% increase in hardness. The bonding process is affected on cold sprayed samples depending on the chosen feedstock particles. The as-sprayed sample composition (ratio of elementary powder content) varies greatly when compared to the original one used for feedstock of pure powders. When the particles suffer heat treatment up to 750°C, solid state reactions were observed on the microstructure.
