Abstract:
AlN–TiB$_2$ composite ceramic samples with a TiSi$_2$ additive are obtained by magnetron sputtering. After deposition, ordered regions in the coatings measure 1 nm across, so that they can be categorized as amorphous-like. Annealing at 900 and 1300$^\circ$C causes crystallization with grain sizes of 11 and 25 nm, respectively. However, crystallization does not dramatically deteriorate the mechanical properties owing to the formation of high-enthalpy phases (AlB$_2$ at 900$^\circ$C and AlB$_3$ at 1300$^\circ$C). The hardness of the coatings varies from 15.1 GPa in the as-prepared samples to 11.0 GPa after annealing to 1300$^\circ$C. This makes it possible to improve the wear resistance of edge tools with these coatings by a factor of 1.32 at a temperature of 1300$^\circ$C near the contact.
