Titanium-Carbide Formation in a Liquid Hydrocarbon Medium by Femtosecond Laser Irradiation

Resumo

A brief description of the properties of titanium carbide, its applications, and established methods for its industrial fabrication are provided. A novel procedure for creating titanium-carbide coatings by subjecting a titanium sample to ultrashort laser pulses in a liquid hydrocarbon medium is described. Details of the experimental procedure are provided and the used laser setup is described. The prepared samples are characterized by scanning electron microscopy and Raman spectroscopy. The specifics of titanium-carbide formation at the boundary of the area subjected to the irradiation of a femtosecond laser are investigated based on Raman-spectroscopy data, and a comparison with a sample of commercial titanium carbide is made.
