Plasma technologies lead innovation in material processing, offering unique solutions for surface modification, coating and thin-film deposition, waste recycling, and new material generation and development. This Special Issue will include contributions that investigate various topics such as the development and optimization of different plasma generators, as well as advancements in plasma flow diagnostics, which is essential for understanding plasma’s behavior when interacting with the materials being processed and our ability to control these processes, with the aim to improve the materials’ properties for a wide range of applications.

We invite contributions that focus on both fundamental studies and applied research in plasma–material interactions. Potential topics include, but are not limited to, the following:

  • Development and characterization of advanced plasma sources;
  • Plasma diagnostics for real-time process monitoring;
  • Numerical simulations of plasma and plasma–surface interactions;

The 2000 series aluminium alloys are an attractive option for lightweight structures, but solidification cracking in fusion welding remains an issue in additive manufacturing technologies. Al-Cu-Li alloys, in particular, have gained considerable attention due to their excellent strength-to-weight ratio and corrosion and fatigue resistance, making them highly suitable for aerospace components. Nevertheless, their narrow solidification range makes them highly susceptible to cracking, porosity formation, and elemental evaporation during fusion-based AM processes. These challenges underscore the necessity for advanced processing technologies and the development of suitable feedstock materials to ensure weld integrity and optimal performance. Although Al–Cu–Li alloys are highly valued in the aerospace sector, the application of wire arc additive manufacturing (WAAM) is currently limited by the lack of commercially available wire compositions. This study focuses on the use of powder metallurgy Al-Cu-Li wires in wire arc additive manufacturing, specifically using plasma metal deposition technology, to explore welding characteristics. This research demonstrates the development of an alternative wire using powder metallurgy for WAAM. Powder metallurgy wires were deposited on 5053 and 7075 aluminium substrates, and their microstructure, chemical composition, and mechanical properties were analysed. Key findings include significant elemental losses of Li and Cu during deposition—approximately 55% and 25%, respectively—as well as noticeable variations in microstructure, porosity, and grain morphology, depending on the substrate. Deposits on the 5083 aluminium exhibited more equiaxed grains and a higher chemical homogeneity compared to those on the 7075 substrate. This work establishes a link between material design and additive manufacturing by demonstrating that powder metallurgy Al–Cu–Li wires can be effectively processed by WAAM, achieving controlled elemental losses and a uniform microstructure that enhances weld integrity in aerospace components.

TiW thin films with superior surface properties were deposited at room temperature using RF magnetron sputtering under low-temperature process conditions. The correlation between bulk plasma characteristics and thin-film properties was investigated as a function of applied RF power (200–600 W) and process pressure (1–10 mTorr). Plasma potential and ion density were measured using a Langmuir probe, while deposition rate, surface roughness, sheet resistance, and crystallinity were evaluated. Increasing the applied RF power simultaneously increased plasma potential and ion density, enhancing ion bombardment energy at both the target and substrate, which improved sputtering efficiency and deposition rate. Under low-temperature deposition, thermal stress induced by differences in thermal expansion between the film and substrate was minimal. However, limited surface diffusion of adatoms caused incomplete coalescence of nucleation islands, adversely affecting film crystallinity. Refractory metals such as tungsten exhibit strong dependence of residual stress and microstructure on deposition conditions, highlighting the importance of plasma and process parameters on TiW film properties. When RF power was increased, the enhancement in deposition rate outweighed the effect of increased ion energy, leading to tensile stress from void formation dominating over compressive stress induced by high-energy ions. This also contributed to increased grain size and reduced sheet resistance. In contrast, variations in process pressure had minor effects on plasma characteristics, resulting in limited changes in the deposited film properties. Full article

Material surfaces are of primary importance in biomaterial development, significantly influencing implant lifespan and clinical success. Consequently, coating technologies are frequently employed to modify surface properties and functionality. Plasma-based amorphous carbon coatings have been widely applied to all classes of substrates to improve their tribology, corrosion resistance, hardness, and even biological properties. Plasma technology is widely recognized to be effective, not only for the deposition of amorphous carbon coatings but also for substrate pre-treatment, in which it may play a key role in activating surfaces and enhancing interfacial adhesion. Amorphous carbon coatings can be classified into two major categories: diamond-like carbon (DLC) and polymer-like carbon (PLC), according to their mechanical properties. Regardless of their nature, the adhesion of both types of amorphous carbon coatings to the substrate has always represented a major challenge. Several strategies have been reported to enhance the adhesion of DLC coatings to silicon wafers, metals, and glass substrates. However, few studies report strategies aimed at controlling the adhesion of (both types of) amorphous carbon coatings to polymeric substrates, polymeric implants, and polymeric devices. Therefore, this work aims to provide a state-of-the-art review on the adhesion of amorphous carbon coatings to polymeric substrates for biomedical applications. Furthermore, this review presents the main techniques used to assess adhesion and the strategies available to improve adhesion between coatings and polymeric substrates. Full article
