“…It is proposed to use the oxygen plasma for the material (glass) treatment to improve surface resistance and dielectric properties of the bulb 10. Our opinion is that the nanoscale modifications of the surface are due to the presence of the oxygen (even in small amounts) in the plasma.…”

The high‐frequency electrodeless light sources (HFELS) are widely used as bright radiators of narrow and intense spectral lines covering the region from VUV to IR. Special HFELS filled with pure helium at pressures from 0.2 to 5 Torr were prepared for diagnostics of interaction between the filling element and the wall material (glass). Pollution of the discharge plasma with the oxygen admixture was studied by spectroscopy. Atomic force microscopy experiments were performed to find modification of the wall surface at the nanoscale level. Release of oxygen by the walls is found to depend strongly on the discharge conditions and significant changes of the surface structure are detected after plasma treatment.

“…Methods used successfully to improve interfacial adhesion in glass fibre-reinforced polymers have involved coupling agent treatments [7–9], plasma etching [10, 11], and plasma polymerisation [12–15] of fibres. However, improving the interfacial strength in biodegradable systems has proved rather challenging due to the degrading nature of the materials concerned.…”

Bioresorbable phosphate glass fibre reinforced polyester composites have been investigated as replacement for some traditional metallic orthopaedic implants, such as bone fracture fixation plates. However, composites tested revealed loss of the interfacial integrity after immersion within aqueous media which resulted in rapid loss of mechanical properties. Physical modification of fibres to change fibre surface morphology has been shown to be an effective method to improve fibre and matrix adhesion in composites. In this study, biodegradable magnesium which would gradually degrade to Mg2+ in the human body was deposited via magnetron sputtering onto bioresorbable phosphate glass fibres to obtain roughened fibre surfaces. Fibre surface morphology after coating was observed using scanning electron microscope (SEM). The roughness profile and crystalline texture of the coatings were determined via atomic force microscope (AFM) and X-ray diffraction (XRD) analysis, respectively. The roughness of the coatings was seen to increase from 40 ± 1 nm to 80 ± 1 nm. The mechanical properties (tensile strength and modulus) of fibre with coatings decreased with increased magnesium coating thickness.

“…Here, the organic contamination resulted to be no greater than several percent of a monomolecular layer in coverage and contact angles were close to surface total wettability. Comparing with control method (Method 1) it is assumed that oxygen plasma treatment (Methods 2 -4) activated glass surface causing the decrease of contact angle from 20° ±2° to ~6° due substitution of chemically active dangling bonds and hydroxyl groups for the carbon contamination in the surface resulting in decreased oxidation as it is reported in [29,30]. It is considered, that the use of Method 7 is also attributed to leaving hydroxyl groups on the glass surface, imparting negative charge to the surface (making it hydrophilic) [10].…”

“…The piranha clean treatments on glass resulted in highly variable contact angles ranging from <8° to 43° in [28], 4° in [13] and 21° to 27° in [14]. Plasma treatment on glass with oxygen reaction gas even at short exposure time resulted in contact angles to be below 10° as it was reported in [29] and [30]. Previous work [14] reported that there was no correlation between surface roughness and contact angle hysteresis, contact angles, or dewpoint error for glass surfaces.…”

Contact angle measurements using method based on B-spline snakes (active contours) were applied to investigate surface wettability properties of commercial soda-lime-silica float glass subjected to various surface preparation methods. The comparative evaluation of vacuum evaporated chromium thin film adhesion strength to float glass treated under different surface preparation methods was performed using scratch tests. Also, the influence of float glass substrate heating for chromium thin film adhesion strength was investigated. Surface activation and contamination removal by O₂ plasma process and RCA-1 surface preparation method revealed the best results, where surfaces were free of hydrophobic contaminants with low contact angles ranging from 4° to 8°. For majority of float glass surface preparation methods the contact angles were observed slightly higher for the “tin side” as compared with “air side”. Soda-lime-silica float glass surface wettability properties of both sides were equalized during bombardment in RIBE unit by Ar⁺ ion beam. O₂ plasma process and RCA-1 surface preparation method for float glass resulted in a higher value of the thin chromium film adhesion to the float glass substrate as measured from the average critical normal force (O₂ plasma 0.169 N; RCA-1 0.14 N) in scratch tests. The float glass substrate heating (100°C) in the vacuum chamber before chromium thin film evaporation process resulted in even higher value of the thin chromium film adhesion to the float glass substrate.
