These coatings were comparatively studied in terms of phase stability after thermal annealing at 250, 500, 750, and 1000\u2009\u00b0C in argon using Raman and x-ray absorption near-edge spectroscopy techniques. The main differences were observed at temperatures above 500\u2009\u00b0C when oxidation processes occur and the mechanical properties deteriorate. At 1000\u2009\u00b0C, the samples were fully oxidized forming a-C, TiO2, and B2O3 as final products. Higher hardness and reduced indentation modulus values and better tribological properties were observed at 750\u2009\u00b0C for nanocomposite structures including amorphous carbon and ternary TiBxCy phases. This behavior is attributed to a protective effect associated with the a-C phase which is achieved by the encapsulation of the nanocrystals in the coating and the better hard\/lubricant phase ratio associated with this type of coating.<\/p>\n","protected":false},"excerpt":{"rendered":"<p>TiBC coatings with different phase compositions (nanocrystalline TiBxCy or TiB2 phases mixed or not with amorphous carbon, a-C) were prepared by magnetron sputtering.
