Nanostructured coatings of metal (tantalum) containing diamond-like carbon (a-C:Ta) have been prepared by femtosecond pulsed laser deposition (PLD). The films, containing 15 at.% tantalum, have been deposited by ablating sequentially graphite and metallic tantalum in vacuum conditions with an amplified Ti:sapphire laser. The coatings have been investigated by X-ray photoelectron spectroscopy, grazing...
Metal-containing diamond-like carbon films (Me-DLC), with metallic particles embedded in a DLC matrix, have become good candidates to improve many film properties (including mechanical properties and adhesion) and to enhance the tribological behavior in severe conditions. Previous studies on the properties of Me-DLC coatings have reported lower compressive stresses and higher wear resistance compared...
