“…The problem of cluster interactions with the surface of a substrate has been widely discussed in many studies [27][28][29][30]. According to them, the nature of these phenomena depends on the kinetic energy of incident clusters, type and temperature of substrate, cluster size and also the direction of the beam relative to the substrate surface, etc.…”

“…According to them, the nature of these phenomena depends on the kinetic energy of incident clusters, type and temperature of substrate, cluster size and also the direction of the beam relative to the substrate surface, etc. All these factors affect the rearrangement and diffusion which may occur on substrate surface [27,28]. The phases present in the coating material were supersaturated solid solutions of bcc and fcc structure, depending on Cu content.…”

Pulsed plasma in the impulse plasma deposition (IPD) synthesis is generated in a coaxial accelerator by strong periodic electrical pulses, and it is distributed in a form of energetic plasma packets. A nearly complete ionization of gas, in these conditions of plasma generation, favors the nucleation of new phase of ions and synthesis of metastable materials in a form of coatings which are characterized by amorphous and/or nanocrystalline structure. In this work, the Fe-Cu alloy, which is immiscible in the state of equilibrium, was selected as a model system to study the possibility of formation of a non-equilibrium phase during the IPD synthesis. Structural characterization of the layers was done by means of X-ray diffraction and conversionelectron Mössbauer spectroscopy. It was found that supersaturated solid solutions were created as a result of mixing and/or alloying effects between the layer components delivered to the substrate independently and separately in time. Therefore, the solubility in the Fe-Cu system was largely extended in relation to the equilibrium conditions, as described by the equilibrium phase diagram in the solid state.

“…The current atomic-level experimental techniques, such as low energy electron diffraction and scanning tunneling microscopy, have allowed the direct visualization of atomic structures of surfaces, but they cannot resolve the kinetic process of atoms at picosecond scale [8,9]; therefore, atomistic simulation has become a valuable complementary method for the study of film growth at atomic scale. Films could grow by atomic units [10] or nanometer-sized clusters [11] during the PVD, which therefore is generally simplified as an atomic deposition process [12] or an atomic cluster deposition process [13]. PVD processes have been modeled via classical molecular dynamics (CMD)simulations based on these two models [12][13][14][15][16][17][18].…”

The interaction processes between incident N or Ti atoms and the TiN(001) surface are simulated by classical molecular dynamics based on the second nearest-neighbor modified embedded-atom method potentials. The simulations are carried out for substrate temperatures between 300–700 K and kinetic energies of the incident atoms within the range of 0.5–10 eV. When N atoms impact against the surface, adsorption, resputtering and reflection of particles are observed; several unique atomic mechanisms are identified to account for these interactions, in which the adsorption could occur due to the atomic exchange process while the resputtering and reflection may simultaneously occur. The impact position of incident N atoms on the surface plays an important role in determining the interaction modes. Their occurrence probabilities are dependent on the kinetic energy of incident N atoms but independent on the substrate temperature. When Ti atoms are the incident particles, adsorption is the predominant interaction mode between particles and the surface. This results in the much smaller initial sticking coefficient of N atoms on the TiN(001) surface compared with that of Ti atoms. Stoichiometric TiN is promoted by N/Ti flux ratios larger than one
