Special Issue Information

Dear Colleagues,

Plasma techniques have revolutionized the fields of materials science, enabling coatings, films and etching in a wide range of areas in surface engineering. The advanced plasma techniques have greatly contributed to the field of nanofabrication by allowing the precise control of nano-scale materials. With these plasma-based techniques, it is possible to deposite or etch thin films of various nano-scale materials for applications of nanoelectronics, photovoltaic and biosensors. Spurred primarily by the growing applications ranging from advanced logic devices, flash memory and magnetoresistive random access memory, nano-electromechanical systems, energy devices, etc., new processes, instruments, diagnostic techniques, and deposition and etching mechanisms are required. Accordingly, we are launching this Special Issue of Coatings that will focus on the fundamentals and applications of advanced plasma techniques for coating, films and etching in addressing the covered subjects.

This Special Issue will collect original research articles and review papers that include, but are not limited to, the following areas:

  • Theoretical, modeling and experimental research, knowledge and new ideas in plasma source, pulsed plasma techniques and radiation sources;
  • Atomic layer processing (ALD/ALE);
  • Dry etching technologies with low-pressure and atmospheric plasmas;
  • Plasma deposition of functional coatings and finishings;
  • High-pressure and thermal plasma processing;
  • Surface reaction and damage with plasma;
  • Nanofabrication and nanodevices using plasma-based techniques;
  • Plasma processing for biomaterial, medical, energy and sensor applications;
  • Plasma processing for new material devices (MRAM, power devices, organics, etc.).

In this work, the TiC-reinforced CoNi alloy coatings were prepared by the plasma spraying method. Their microstructure, high-temperature oxidation, and thermal shock resistance at 900 °C were studied. The results showed that the CoNi alloy coating exhibited a single phase (c-Co-Ni-Cr-Mo). After adding Ti-graphite mixed powders, the sprayed coating exhibited TiC and TiO2 phases, besides the c-Co-Ni-Cr-Mo matrix phase. For CoNi alloy coating, the main oxidation products were Cr2O3 and CoCr2O4 (NiCr2O4). For TiC-CoNi alloy coating, the main oxidation products were the TiO2 phase, coupled with Cr2O3 and CoCr2O4 (NiCr2O4) phases. The content of oxides increased with the oxidation time. The oxidation weight gain of the TiC-CoNi composite coating was slightly higher than that of the CoNi alloy coating. The formation of TiC could improve the thermal shock resistance of the CoNi alloy coating. Full article

Lead titanate thin films of pyrochlore phase were deposited using layer-by-layer reactive magnetron sputtering on a heated platinized silicon substrate. It was found that the pyrochlore phase transition to the perovskite phase was initiated at 700 °C, and the properties of the PbTiO3 films could be controlled by changing the annealing environment. The thin films annealed in air and oxygen environments (1.33 Pa) have a tetragonal structure. The highest values of remnant polarization and the coercive field were 38 μC/cm2 and 130 kV/cm, respectively, but the largest dielectric loss was determined for the films annealed in air. The remnant polarization, coercive field and dielectric loss were reduced when the annealing of films was performed using oxygen gas at 1.33 Pa pressure. The films annealed in vacuum showed a rhombohedral (and ferroelectric) structure with the lowest remnant polarization and coercive field values. Such a structure was not observed for lead titanate at room temperature. It was observed that the surface morphology strongly depended on the reaction rate, which was influenced by the oxygen concentration in the environment. Full article

The use of high-power impulse magnetron sputtering (HIPIMS) to deposit chromium-based thin films on brass substrates for the purpose of corrosion-protective coating was investigated. By varying the process parameters (pulse frequency, pulse width and N2 flow rate) and structure design, including single-layer and multilayer structures, the obtained results revealed that the Cr-N films deposited through the use of HIPIMS exhibited higher film density and corrosion resistance compared to traditional direct-current magnetron sputtering. Based on the results of a field test using copper-accelerated acetic acid solution, the Cr-N film with a multilayered structure can further extend the time to corrosion onset. This is because the bottom layer in the multilayer structure can block structural defects in the layer above it, effectively reducing the penetration of corrosive agents into the substrate. The high bias voltage, coupled with increased temperature during deposition, led to a dezincification effect, resulting in the reduced adhesion of the film to the substrate and decreased overall corrosion resistance.

The plasma spray method is widely utilized for enhancing wear, surface fatigue, and corrosion properties through coating. The mechanical and surface characteristics of the resulting coating are contingent upon various spraying parameters, including arc current, working current, spraying distance, and plasma gun traversing speed. This study investigates the impact of these manufacturing parameters on the porosity, hardness, and bond strength of a coating produced from an Al-Ni alloy applied to a Q235 steel substrate. An extensive experimental program was conducted to analyze the influence of these parameters on the coating properties. Consequently, a preferred combination of parameters, identified through a comprehensive evaluation method, yielded greater performance benefits compared to the orthogonal experimental groups.
