TL;DR: In this paper, a thermal investigation of reactive cathodic arc evaporated coatings and elucidate the diverse performance of monolithically grown TiAlN, TaAlN and TiAlTaN, and a multilayered architecture of TiAl N and TaAl N layers.

TL;DR: In this article, the authors have developed arc-evaporated Ti 1−x−y Al x Ta y N coatings with various Al (x = 0.50−0.65) and Ta (y= 0.00-0.15) contents.

TL;DR: In this article, the impact of varying Al and Y content on the industrially preferred cubic structure of Ti 1−− x Al x N was studied using a plasma-assisted reactive magnetron sputtering process and the thermal stability of coatings with single-phase cubic structure was carried out by annealing experiments in vacuum and ambient atmosphere.

TL;DR: In this paper, the interaction of bias potential and Al content on structure, hardness, thermal stability, and oxidation resistance of arc evaporated Ti 0.49 Al 0.44 Zr 0.07 N hard coatings was studied.

TL;DR: In this paper, the influence of alloying Y, Zr, or Ta on the phase formation during oxidation and their potential to form protective oxide scales was studied, by combining differential-scanning-calorimetry, thermo-gravimetric-analysis, and X-ray diffraction.
