dc.description.abstract | The difculty of getting a correct distribution of the reinforcement in the metal matrix and the complexity for achieving
a good-metallurgy matrix-reinforcement bonding has limited the development of additive manufacturing of metal matrix
composites. This research proposes the use of a reactive atmosphere during the fabrication process to obtain titanium matrix
composites reinforced with TiN. The relation between the carrying gas and the process parameters used with the presence of
porous and defects, the microstructure, and microhardness has been obtained. Nitrogen was used as the carrying gas of the
titanium powder. Under laser irradiation, the particles melt and react with nitrogen, resulting in the formation of a titanium
matrix composite highly reinforced with TiN. The composite obtained had a microhardness increase between 50 and 100%
in comparison with titanium samples fabricated in the same conditions in an argon atmosphere. Three reaction mechanisms
have been proposed to take place in the microstructure, depending on the amount of nitrogen in the titanium particles, and
its difusion in them during the manufacture. | es |
