“…Hollow cathodes [91] enhanced by the auxiliary magnetic field generated by the external system of the magnetic coils [92] (neutral-loop discharge [93], e.g.) may also be used to confine and guide the plasma or to conduct a duplex treatment [94,95]. An equipment to supply various types of the electrical power such as DC, single-or double-frequency RF, pulsed high-voltage bias, etc., are also considered as the necessary facility to provide the range of the ion energies to the wafer with the treated materials.…”

Plasma and metamaterials: what new advances in space micro-propulsion systems can they bring when used together? The aim of this concise review article is to attract attention of the space propulsion scientists and engineers, along with experts working in the fields of micromachines, optics, communication, and other hi-tech devices, to the opportunities that arise from different possible combinations of plasma and metamaterials. Along with plasma-based techniques used for the fabrication of complex metamaterials, we examine two unusual plasma/ metamaterial systems, namely when plasma interacts with a metamaterial, and when plasma itself features some properties of a metamaterial. The fundamental physics behind the principal processes that define the behavior of these systems is briefly outlined. Possible applications in space technology, mainly for micro-propulsion systems for Cubesats and small satellites are also sketched.

“…[46][47][48] The nitriding process can provide a significantly high wear and adhesion resistance for TiAlN coatings. 49 Therefore, in this study, in addition to carburizing, a nitriding process was also applied to some samples to determine its synergistic effect on the abrasive wear behaviour of thin hard coatings. The nitriding process parameters are given in Table 1.…”

“…In this study, a series of gradient Ta coatings were prepared on TC4 substrate by plasma alloying technique. The influence of alloying temperature (750, 800, and 850 • C) and time (10,30,60, and 120 min) on surface morphology, the thickness of the deposition layer (DPL) and diffusion layer (DFL), and the interfacial strength of Ta coatings were systematically investigated. Furthermore, Ta coatings prepared at the optimized alloying temperature of 800 • C with superior interfacial strength were characterized in microhardness, wear resistance, corrosion resistance, and cytocompatibility.…”

Plasma alloying technique capable of producing metallic coatings with metallurgical bonding has attracted much attention in dental and orthopedic fields. In this study, the effects of temperature and time of plasma tantalum (Ta) alloying technique on the mechanical, electrochemical, and osteoblastic properties of Ta coatings were systematically investigated. Ta coatings prepared at 800 °C possess better interfacial strengths than those prepared at 750 and 850 °C, and the interfacial strength increases with prolonged alloying time (30–120 min). At 800 °C, however, the increased proportion of the soft Ta deposition layer with alloying time in the whole coating impairs the surface mechanical properties of the entire coating, as convinced by decreased microhardness and wear resistance. Moreover, Ta coatings exhibit better corrosion resistance than the Ti6Al4V substrate in Dulbecco’s modified Eagle medium. The enhanced adhesion and extracellular matrix mineralization level of osteoblasts demonstrate the better cytocompatibility and osteogenic activity of the Ta coating. Ta30 (Ta coating prepared at 800 °C for 30 min) exhibits excellent mechanical, electrochemical, and osteoblastic behaviors and is promising in biomedical applications.
