Special Issue Information

Dear Colleagues,

Physical vapor deposition (PVD) is a vacuum deposition method of producing thin films and coatings. In a PVD process, the source material is changed from the solid phase to the vapor phase and then is deposited on a substrate surface, by returning to a condensed phase. The most common PVD processes are evaporation and sputtering with the assistance of various of techniques. PVD technology is applied in applications that require thin films or coatings for mechanical, physical, chemical, optical, and electronic functions. PVD technology is developing with advances in theory and technique, and providing extensive opportunities for advanced thin films and coatings in an expanding area of applications. This Special Issue of Coatings on "Physics Vapor Deposition" is open to all original research and critical reviews on the latest advances on all aspects of PVD.

In particular, the topics of interest include, but are not limited to:

  • PVD physics and modeling
  • PVD processes, technoques, and equipment
  • PVD coating characterization
  • PVD coating properties, behaviors, and performances
  • PVD coating applications

Zirconium diboride (ZrB2) thin films were deposited on a Si(100) substrate using pulsed direct current (dc) magnetron sputtering and then annealed in high vacuum. In addition, we discussed the effects of the vacuum annealing temperature in the range of 750 to 870 °C with flowing N2 on the physical properties of ZrB2 films. The structural properties of ZrB2 films were investigated with X-ray diffraction (XRD), field emission scanning electron microscopy (FE-SEM), transmission electron microscopy (TEM), atomic force microscopy (AFM), and X-ray photoelectron spectroscopy (XPS). The XRD patterns indicated that the ZrB2 films annealed at various temperatures exhibited a highly preferred orientation along the [0001] direction and that the residual stress could be relaxed by increasing the annealing temperature at 870 °C in a vacuum. The surface morphology was smooth, and the surface roughness slightly decreased with increasing annealing temperature. Cross-sectional TEM images of the ZrB2/Si(100) film annealed at 870 °C reveals the films were highly oriented in the direction of the c-axis of the Si substrate and the film structure was nearly stoichiometric in composition. The XPS results show the film surfaces slightly contain oxygen, which corresponds to the binding energy of Zr–O. Therefore, the obtained ZrB2 film seems to be quite suitable as a buffer layer for III-nitride growth. Full article

The application of surface treatments that incorporate silver or copper as antibacterial elements has become a common practice for a wide variety of medical devices and materials because of their effective activity against nosocomial infections. Ceramic tiles are choice materials for cladding the floors and walls of operation rooms and other hospital spaces. This study is focused on the deposition of biocide physical vapor deposition (PVD) coatings on glazed ceramic tiles. The objective was to provide antibacterial activity to the surfaces without worsening their mechanical properties. Silver and copper-doped chromium nitride (CrN) and titanium nitride (TiN) coatings were deposited on samples of tiles. A complete characterization was carried out in order to determine the composition and structure of the coatings, as well as their topographical and mechanical properties. The distribution of Ag and Cu within the coating was analyzed using glow discharge optical emission spectrometry (GD-OES) and field emission scanning electron microscope (FE-SEM). Roughness, microhardness, and scratch resistance were measured for all of the combinations of coatings and dopants, as well as their wettability. Finally, tests of antibacterial efficacy against Staphylococcus aureus and Escherichia coli were carried out, showing that all of the doped coatings had pronounced biocide activity. Full article

Abstract: The article deals with a determination of influence of mechanical treatments on a quality and wear resistance of coated cutting tool. Cutting inserts made from a sintered carbide with a deposited layer of PVD coating were selected for a measurement. Non-homogeneity caused by a creation of macroparticles arises in application layer during process of applying of coating by PVD method. These macroparticles make a surface roughness of PVD coating worse, increase a friction and thereby a thermal load of cutting tool also. Also, the macroparticles could be the cause of a creation and a propagation of microcracks in a coating and can cause quick cutting tool wear during machining. The mechanical surface treatments were suggested for an improvement of surface integrity of deposited layers of PVD coating, namely technology of drag finishing and abrasive jet machining. After their application, the areal surface roughness was measured on surface of coated cutting inserts, an occurrence of macroparticles was tracked and a surface structure was explored. A durability test of cutting inserts was carried out for a verification of the influence surface treatment on wear resistant of cutting inserts during milling process. The cutting inserts with a layer of PVD coatings termed as samples A, B, and C were used for the durability test. The first sample A represented the coating before the application of mechanical surface treatment and the samples B and C were after the application of mechanical surface treatment. A carbon steel termed C45 was used for milling process and cutting conditions were suggested. A visual control of surface of cutting inserts, an intensity of wear and an occurrence of thermal cracks in deposited PVD layers were a criterion for evaluation of the individual tests.
