Interaction of femtosecond laser radiation with titanium in a liquid hydrocarbon medium

Abstract

A method for the synthesis of microspheres coated with titanium carbide is described. The processes occurring in the region of the action of laser radiation are considered. The formation of microspheres was carried out by the action of femtosecond laser radiation on the surface of titanium located in the reaction medium - the ultimate hydrocarbon. The hydrocarbon source was the medium in which the treatment was carried out. The obtained microspheres have an average size of 1-3 μm and can be used in applications of additive engineering, powder metallurgy as the main raw material, or as an alloying additive.

Formation of Titanium Nitride, Titanium Carbide, and Silicon Carbide Surfaces by High Power Femtosecond Laser Treatment

“…SiC nanoparticles have been obtained with femtosecond laser irradiation of silicon immersed in hexane or ethanol, respectively [25,26] . A similar process has been applied on titanium immersed in hexane for the synthesis of TiC microparticles [27] . Longer pulses have been used to ablate titanium in a methane atmosphere and to deposit the resulting TiC as a film on silicon targets [28] .…”
