“…Alloying of Zr element into CrN ceramic thin films has attracted much interest since ZrN film is a protective film due to its high hardness, and high corrosion and wear resistance [3,4]. It has been shown that the incorporation of Zr could enhance the film hardness and wear resistance and decrease surface roughness [5][6][7]. Kim et al.…”

CrN and CrZrN ceramic thin films were produced by a planar type reactive sputtering system on glass and stainless steel substrates. We investigated oxidation resistance of CrN and CrZrN ceramic thin films with different Zr contents. The structure of the films at different thermalannealing temperatures was investigated by X-ray diffraction (XRD), atomic force microscopy (AFM) and scanning electron microscopy (SEM). The mechanical properties of the films at different thermal-annealing temperatures were measured by nano-indentation. The results of this study showed that the addition of few amount of Zr (0.4 at%), can improve thermal stability of CrZrN ceramic thin film and increase the oxidation temperature of the film from 600 o C to 800 o C. The relatively good oxidation resistance (800 o C) and high hardness of the film with the lowest Zr content, indicates that this film is a good candidate for high temperature applications.

“…Because of the strict demands for practical applications under ever larger mechanical stresses and higher temperatures, more robust coatings have been investigated to replace conventional single-layered, single-phase, unitary metals or metallic compounds (such as TiN, CrN, TiC, etc. ), by introducing stacked structures (TiN/TiC, TiC/VC, TiCN/ZrCN [2][3][4]), nanocomposite structures (nc-TiN/a-Si 3 N 4 , nc-TiN/a-BN, nc-TiN/a-Si 3 N 4 /TiSi 2 , where nc = nanocrystalline, a = amorphous [5,6]), and/or multiple components (ternary CrZrN, ZrCN, CrCN, TiCN [7][8][9][10], and quaternary TiAlCN, TiSiCN [11,12]), as well as forming stacked, multi-component nanocomposite structures (TiAlN/TiN/Al 2 O 3 [13]) with good mechanical performance. In recent years, Yeh developed a new alloy system, named "high-entropy alloy" (HEA), which is composed of five or more metallic elements in an equimolar or near-equimolar ratio [14].…”

Abstract:In this study multi-component (AlCrTaTiZr)N x Si y high-entropy coatings were developed by co-sputtering of AlCrTaTiZr alloy and Si in an Ar/N 2 mixed atmosphere with the application of different substrate biases and Si-target powers. Their nanomechanical properties and deformation behaviors were characterized by nanoindentation tests. Because of the effect of high mixing entropies, all the deposited multi-component (AlCrTaTiZr)N x Si y high-entropy coatings exhibited a simple face-centered cubic solid-solution structure. With an increased substrate bias and Si-target power, their microstructures changed from large columns with a [111] preferred orientation to a nanocomposite form with ultrafine grains. The hardness, H/E ratio and H 3 /E 2 ratio of (AlCrTaTiZr)N 1.07 Si 0.15 coating reached 30.2 GPa, 0.12 and 0.41 GPa, respectively, suggesting markedly suppressed dislocation activities and a very high resistance to wear and plastic deformation, attributable to grain refinements and film densification by the application of substrate bias, a nanocomposite structure by the introduction of silicon nitrides, and a strengthening effect induced by severe lattice distortions. In the deformed regions under indents, stacking faults or partial dislocations were formed, while in the stress-released regions, near-perfect lattices recovered.
