Abstract

The main objective of this research work was the growth of Titanium Carbide and Titanium Diboride hard coatings on tool steels with Pulsed Laser Deposition (PLD) in order to improve their surface mechanical properties. A pulsed KrF excimer laser was used with the deposition chamber at a base pressure of 10⁻⁶ mbar. The morphology and the microstructure of the coatings were examined using Scanning Electron Microscopy, X Ray Diffraction and Transmission Electron Microscopy.
