“…Recently, the properties of multicomponent coatings, sometimes called "highly entropic" coatings, have been extensively studied. In particular, the following coatings were investigated (Ti,V,Cr,Zr,Hf)N [15,16], (Al,Cr,Ta,Ti,Zr)N [17], (Al,Cr,Nb,Si,Ti,V)N [18], and (Zr,Nb,Cr,Al)N [19]. In these studies, it was shown that the addition of alloying elements (in particular, Nb, Cr, Nf, Ta) to the Zr-N, Al-N or Ti-N nitride systems reduces the average cavitation velocity and abrasive wear of the coatings.…”
