Effects of substrate temperature on the structure and mechanical properties of (TiVCrZrHf)N coatings

Effects of substrate temperature and carbon content on the structure and properties of (CrCuNbTiY)C multicomponent coatings

“…At 80°C, due to low surface mobility, the coating morphology develops as tapered crystallites from a reduced number of nucleation sites, resulting small grain size values, specific for the MPE coatings [48]. With increasing temperature at 300°C, the surface diffusion and adatom mobility also increase, leading to an enhanced aggregation of crystallites [2,6,49,50], more evident for series-1 coatings. For this series, the coatings deposited at higher temperatures than 300°C showed a continuously decrease of the grain size, partially as a result of changes in grain growth kinetics [48,51].…”

“…Various nitride MPE films were investigated so far, e.g. [1][2][3][4][5][6][7], but less attention was given to carbides [8][9][10].…”

“…The last decade has witnessed the rapid progress in the development of multi-principal-element (MPE) hard films [1][2][3][4][5][6][7][8][9][10]. Based on the principle of high-entropy alloys [11,12], comprising at least five principal metallic elements in near-equal atomic ratios, MPE nitride or carbide coatings have been increasingly investigated due to their unique combination of structural, mechanical and wear-corrosion-oxidation resistant characteristics.…”

Microstructure and Properties of Coating of FeAlCuCrCoMn High Entropy Alloy Deposited by Direct Current Magnetron Sputtering

“…In recent years, HEA films have been widely studied, such as TiVCrZrHf film 5 , AlCrMoTaTiZr film 6,7 , etc. Moreover, HEA coatings have been proposed for the potential applications as protective films [8][9][10] , wear-resistant materials 11 , corrosion-resistant materials 12 , and coatings in communication devices 13 .…”

Influence of Thickness of Multilayered Nano-Structured Coatings Ti-TiN-(TiCrAl)N and Zr-ZrN-(ZrCrNbAl)N on Tool Life of Metal Cutting Tools at Various Cutting Speeds

“…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.…”
