Nanostructured smart coatings (NSC) based on the TiAlSi-CN composite structure elements were deposited using advanced reactive physical vapor deposition (PVD) method. The novel NSC on steel substrates demonstrated enhanced wear and corrosion resistance required for multifunctional high-tech applications. The deposited NSC containing TiAlSi-CN nanoparticles strengthened by Cr, Nb and Hf additives exhibited a coefficient of friction (CoF) less than 0.2 and wear rate as low as 10E-8 mm3/Nm. In addition, some self-healing properties were observed preventing denitrification of the core carbon-nitride (CN) layer due to specific tribochemical reactions of Al and Si constituents. Thus, the chemical composition and tentative nano-structure of the NSC can be described by a stoichiometric formula TiAlSi-CN:Me/a-CxNy:Si3N4, where Me=Cr, Nb or Hf.
