抄録

<jats:p>(Ti,Al)N coatings with several Ti/Al ratios were deposited on Si and WC–Co substrates by the cathodic arc ion plating method. The crystal structure was found to be cubic B1 type, which is isostructural with the titanium-based nitrides. Morphology of the (Ti0.4Al0.6)N and TiN films was investigated, using transmission and scanning electron microscopy. The films seemed to have a less columnar structure than expected. The (Ti,Al)N films containing less than 75 mol % AlN had higher hardness than for the pure TiN films. Similarly, (Ti,Al)N coatings displayed superior oxidation resistance at elevated temperatures. Overall, (Ti,Al)N coated cutting tools offer significantly better performance characteristics compared to the tools with TiN coatings.</jats:p>
