“…A variety of candidate elements, including V [57] , Ta [58] , Zr [59] , Y [60] , Hf [61] and Nb [62] , have been considered, but no clear consensus on a screening criterion has been reached. A precise delineation of the phase transformation pathways for TM-Al-X-N quaternary systems is crucial for establishing such a criterion.…”

“…З метою підвищення корозійної стійкості плівок TiAlN з кубічною структурою до складу покриття додавали різні легуючі елементи, такі як Cr [6][7][8], Si [9,10], Nb [11], Ta [12,13], Y [14], Zr [15], або Hf [16]. Більшість результатів показала, що додавання цих елементів у мольній частці <0,1 має найбільш позитивний вплив на характеристики механічної та термічної стійкості.…”

“…The 0 K thermodynamics of quaternary transition metal nitride (Ti-Al-X-N, X=Zr,Hf,V,Nb,Ta) alloys has recently been investigated by Holec using ab initio simulations [86]. Zr improves the oxidation resistance and the as deposited hardness of Ti 1−x Al x N [87,88]; Hf leads to an inferior oxidation resistance of Ti 1−x Al x N and promotes the formation of cubic domains, however it retards the formation of stable wurtzite AlN during thermal annealing [89,90]; The addition of V to Ti 1−x Al x N hard coatings enables lubricating effects based on oxidation resistance and improves the overall wear resistance [91][92][93]; Nb and Ta are also favored due to combining outstanding mechanical properties with good oxidation resistance [94][95][96].…”
