“…The decrease observed in OCP values in the untreated sample indicates that the passive oxide layer is damaged. On the other hand, the shift in the anodic direction observed in bilayer coating shows that the surface is thermodynamically stable with a protective effect [44].…”

In this study, using commercial pure titanium (Cp-Ti) samples, monolayer TiO2, and bilayer TiO2-SiO2 coatings were produced. The aim of this study is to compare the effect of monolayer and bilayer coatings on corrosion and tribocorrosion behaviors of the preferred Cp-Ti material which is preferred especially in applications such as dental implants at different temperatures in simulated body fluid (SBF). XRD and SEM were used for the structural characterization of the coatings. Then, the adhesion strengths of monolayer and bilayer coatings were investigated. Corrosion and tribocorrosion performances of the coatings were carried out at different temperatures due to the change in oral environment temperature due to hot food and drinking consumption. Adhesion strengths corrosion and tribocorrosion performances of untreated, monolayer, and bilayer Cp-Ti samples were examined, and the best performance was seen in the bilayer coatings.

“…Extensive studies have shown the promising potential for the fabrication of oxide or non-oxide ceramics, derived from specific polymer precursors. As reported in our earlier work 22 , one kind of preceramic polymer called perhydropolysilazane (PHPS), has a repeated structure of [-H 2 Si-NH-] n and can be converted into SiON or SiO 2 under Nitrogen and air conditions, respectively. The molar ratio of x and y in SiO x N y is dependent on the annealing temperature and conditions 23 .…”

With the rapid development of electromagnetic (EM) wave circuit devices, high-performance wave-transparent materials with various functions have attracted great attention. Ceramic material is a promising candidate to be applied in harsh environments because of its chemical and corrosion resistance. In this work, a polymer-derived route was adopted to synthesize ceramic composite at room temperature. The composite is made of perhydropolysilazane-derived SiON ceramic and reinforced with boron nitride nanotubes (BNNTs) sheets. With the addition of SiON ceramic materials, the resultant sample showed an excellent hydrophobicity with a contact angle of 135–146.9°. More importantly, superior thermal stability at 1600 °C in the oxygen-containing atmosphere was observed for the fabricated SiON/BNNTs sample, without any shape change. The electromagnetic transparency of the SiON/BNNTs was studied through the waveguide method. The prepared SiON/BNNTs sample has an average real permittivity between 1.52 and 1.55 and an average loss tangent value in the range of 0.0074–0.0266, at the frequency range of 26.5–40 GHz. The effect of thickness on the wave transparency of SiON/BNNTs samples is also discussed. To summarize the aforementioned superior characterization and measurement results, the presented SiON/BNNTs material system has a great potential to be used as EM transparent materials in harsh conditions.

“…[10,[21][22][23][24] PHPS is a nontoxic and low-cost material that is also widely used as barrier coating for passivating steel or silicon surfaces (including photovoltaics). [25][26][27][28] The backbone of this inorganic polymer class consists of silicon and nitrogen atoms (SiNH 2 -NH) and thus can be converted to silica by exposure to water vapor or reactive oxygen species. [29] Hence, this material is suitable to form dense, homogenous, and defect-free silica films from solution-based processes.…”

Organic electronic devices (OEDs) are prone to oxygen‐ and water‐induced degradation and therefore need to be encapsulated with barrier materials. In this work, an aerosol jet (AJ)‐printing process is developed to coat perhydropolysilazane (PHPS) directly onto OEDs by adapting the print setup and systematically optimizing the process parameters. Furthermore, a novel curing process that converts PHPS to silica barrier layers is developed by combining damp heat (DH) exposure with subsequent vacuum–UV irradiation. This two‐step treatment is shown to be considerably faster and gentler than the state‐of‐the‐art curing processes and also yields a quantitatively higher conversion. Both the printing and the conversion process are fully compatible with OED devices, which is demonstrated by a damage‐free direct encapsulation of organic solar cells. The encapsulated cells show a significant reduction of degradation in DH conditions (65 °C/85% r.h.), maintaining >95% of their initial performance for >100 h. Complementary electroluminescence measurements reveal that the AJ‐printed barrier layers effectively prevent lateral water ingress into the devices. Herein, the proof of principle is provided that AJ printing can be used to print barrier layers directly onto OEDs and is thus an industrially highly relevant technology to precisely encapsulate such devices even on 3D objects.
