“…113,114 C. Control of film microstructure and interface engineering Polycrystalline films grown by PVD techniques exhibit a variety of microstructures with respect to the size, the morphology, and the relative orientation of the crystallites. 91,119 These features have, for instance, implications for the mechanical strength 120 and the electrical conductivity 94,95,121 of the film. The microstructure is determined primarily by surface and bulk diffusion processes, 91,119 which are controlled by the deposition temperature, the bombardment by energetic species, and the incorporation of impurities that act as inhibitors for the crystal and grain growth.…”

An introduction to thin film processing using high-power impulse magnetron sputtering

High-power impulse magnetron sputtering (HiPIMS) is a promising sputtering-based ionized physical vapor deposition technique and is already making its way to industrial applications. The major difference between HiPIMS and conventional magnetron sputtering processes is the mode of operation. In HiPIMS the power is applied to the magnetron (target) in unipolar pulses at a low duty factor (andlt;10%) and low frequency (andlt;10 kHz) leading to peak target power densities of the order of several kilowatts per square centimeter while keeping the average target power density low enough to avoid magnetron overheating and target melting. These conditions result in the generation of a highly dense plasma discharge, where a large fraction of the sputtered material is ionized and thereby providing new and added means for the synthesis of tailor-made thin films. In this review, the features distinguishing HiPIMS from other deposition methods will be addressed in detail along with how they influence the deposition conditions, such as the plasma parameters and the sputtered material, as well as the resulting thin film properties, such as microstructure, phase formation, and chemical composition. General trends will be established in conjunction to industrially relevant material systems to present this emerging technology to the interested reader.Funding Agencies|Swedish Research Council (VR)|623-2009-7348

“…The 1 rpm multilayer, which has the longest period ⌳ =25 + 50 nm, exhibits a lower hardness compared to the other two multilayers which is expected due to longer dislocation pile-ups and a less efficient multilayer hardening. 11 All Al-containing coatings exhibit age hardening when annealed above 800°C. Strain fields as a result of the coherency and molar volume difference between c-TiN and c-AlN effectively hinder dislocation motions and increase the hardness.…”

“…The drawback with such approach is the introduction of a component, TiN, which has substantially lower high temperature mechanical properties and overall lower hardness. On the other hand, multilayer/laminated coating structures have proven to exhibit hardening 10 due to shear modulus differences between the layers 11 and coherency strain at the internal interfaces. 12 The introduction of nanometer-thick sublayers results in a Hall-Petch type 13,14 strengthening of the multilayer where the hardness increases due dislocation pile-ups at the internal interfaces.…”

Cubic metastable Ti 0.34 Al 0.66 N / TiN multilayer coatings of three different periods, 25+ 50, 12+ 25, and 6 + 12 nm, and monoliths of Ti 0.34 Al 0.66 N and TiN where grown by reactive arc evaporation. Differential scanning calorimetry reveals that the isostructural spinodal decomposition to AlN and TiN in the multilayers starts at a lower temperature compared to the monolithic TiAlN, while the subsequent transformation from c-AlN to h-AlN is delayed to higher temperatures. Mechanical testing by nanoindentation reveals that, despite the 60 vol % TiN, the as-deposited multilayers show similar or slightly higher hardness than the monolithic Ti 0.34 Al 0.66 N. In addition, the multilayers show a more pronounced age hardening compared to the monolith. The enhanced hardening phenomena and improved thermal stability of the multilayer coatings are discussed in terms of particle confinement and coherency stresses from the neighboring TiN-layers.

“…While nitrides of single elements are studied well enough, their multilayer modifications need study that is more detailed [26][27][28][29][30][31][32][33][34][35]. Therefore, the study of features of structure, elemental and phase composition of multilayer coatings depending on the deposition conditions is an important task in solid-state physics and materials science [36][37][38][39][40][41][42][43][44][45][46][47][48][49][50][51].…”

The studies of the structure and properties of nanoscale multilayer coatings based on the nitrides of refractory metals are summarized in a brief review. By the example of TiN/MoN, TiN/ZrN, CrN/MoN, and more complex (multilayer) (TiZrNbTaHf)N/WN:(TiZrNbTaHf)N/MoN obtained by vacuum-arc deposition of cathode, the dependences of their hardness, wear resistance, friction, corrosion, and oxidation on conditions of the deposition and layers' thickness are investigated and analysed. The regularities of the structure and behaviour properties of such nanoscale multilayer coatings depending on the size of nanograins, textures, and stresses arising in these coatings are described.У короткому огляді узагальнено результати досліджень структури та влас-тивостей наномасштабних багатошарових покриттів нітридів тяжкотоп-ких металів.
