We have developed hard self-lubricant coatings combining a hard matrix (TiN) and a self-lubricant phase in the form of inorganic-like WS2 fullerene. The nanoparticles were injected from the preparation chamber directly to the sample surface during reactive sputtering from a Ti target in Ar/N2 atmosphere. The injection of the particles led to the local oxidation of the matrix due to the flow of residual oxygen from the preparation chamber; therefore, the final composite was TiN/Ti–O–WS2. The observation of the composite film by scanning and transmission electron microscopies showed the incorporation of the WS2 nanoparticles; however, their bonding with the matrix was weak. The analysis of the wear tracks did not show any presence of WS2 in the contact.
