    Highly wettable films plasma-polymerized from ethylene oxide (1987)
    Bognor Regis [u.a.] : Wiley-Blackwell

    Notizen: Highly wettable films were prepared by plasma-polymerization from ethylene oxide. The surface energy of the formed films is 65.6 dyn/cm, and the contact-angle of water on the films is 12 degrees. The formation of highly wettable films is limited to the plasma-polymerization conducted at low W/FM values of below 200 MJ/kg. Analyses by infrared spectroscopy and ESCA show that the formed films contain much oxygen residues such as C—O, C—O, and C(O)—O— groups. Such polar groups would contribute high wettability of the plasma-films from ethylene oxide.

    Notizen: Polymeric films were deposited on Al2O3 ceramic substrates by plasma deposition from trimethylsilyldimethylamine (TMSDMA) and bis(dimethylamino)methylvinylsilane (BDMAMVS), and their capacitance-relative humidity characteristics investigated. Films doped with methylbromide showed a linear dependence of log(capacitance) with relative humidity over the range 20-90% suggesting application on a moisture sensor device. Hysterisis effects were negligible and the response time was within 1 min.

    Quantitative GDOS analysis of oxide films on steels (1994)
    Chichester [u.a.] : Wiley-Blackwell

    Thema: Physik
    Notizen: A method for the quantitative analysis for oxide films on steels by means of glow discharge optical emission spectrometry (GDOS) was investigated. Effective optical emission yields for analysed elements were determined by measuring the emission intensities and sputtering rates of standard samples during discharging under constant conditions. The chemical composition in oxidized samples was obtained from the emission intensities and the effective emission yields, while the sputtered depth was calculated from the emission intensities and effective densities of elements. From measurements of the sputtering of magnetite the effective density for oxygen was estimated as 1820 kg m-3. It was shown that GDOS can be used to determine the quantitative composition and the thickness of the oxide layers on steels.

    Application of glow discharge optical emission spectroscopy to diffusion measurement of copper in ferritic and austenitic iron and steels (1992)
    Chichester [u.a.] : Wiley-Blackwell
    Surface and Interface Analysis 19 (1992), S. 638-642 
    Details

    Thema: Physik
    Notizen: Glow discharge optical emission spectroscopy (GDOS) is a method to analyse the optical emission of elements during sputtering of a solid, providing data on the light intensities of the elements vs. the sputtering time. By correcting the measured light intensities with standard samples, it is possible to obtain the quantitative depth profile up to about 100 μm. In the present research, GDOS was applied to the diffusion measurement of impurity atoms in metals and alloys. After a thin film of copper was coated on iron and steels, the surface film was diffused into the matrix at high temperatures. The penetration curves of copper from the surface were obtained from the GDOS data. Diffusivities of copper in ferritic and austenitic regions of iron were determined from the penetration curves, which were in agreement with previous results. Diffusion of copper in commercial ferritic and austenitic stainless steels was also examined. The diffusivities obtained were comparable with those expected from the temperature dependence of the diffusivities in the ferritic and austenitic phases of pure iron.

    Quantitative trace analysis by non-resonant laser post-ionization (1991)

    Notizen: In order to overcome the poor quantitativeness of conventional SIMS, sputtered neutral mass spectrometry (SNMS) employing non-resonant laser post-resonant laser post-ionization has been studied. By studied. By combining a time-of-flight (TOF) analyzer with a powerful excimer laser, it was confirmed that non-resonant laser post-ionization is capable of quantitative analysis of impurities at the pm level. On comparing laser wavelengths, 193 nm (ArF) gave a higher post-ionization efficiency than 248 nm (KrF). It was also demonstrated that the electronegative element sulphur can be detected as positive ions by post-ionization. Furthermore, surface metallic contaminants in a small area (250 μm square) could be determined down to 1011 atoms cm-2.

    AES/GDS characterization of thin oxide films on Fe—Cr sheet steels (1991)

    Notizen: Thin oxide films on four kinds of commercial sheet were characterized with Auger electron spectroscopy (AES) and glow discharge optical emission spectroscopy (GDS). Enrichment of alloying elements was noticed in the thin oxide films formed in air. The depth profiles obtained by AES with ion sputtering showed that enrichment of chromium occurred at the interface between the oxide and the matrix. It was difficult with AES to obtain the profiles of silicon and manganese because of overlap of their peaks with the iron peaks on the spectrum. On the other hand, with GDS, silicon and manganese could be analysed quantitatively in thin films that are 〈0.05 μm thick.

    Notizen: Colorless, transparent, and filmy polymers prepared from mixtures of tetramethylsilane (TMS) and ammonia gas (NH3) were investigated by elemental analysis, infrared (IR) spectroscopy, and ESCA. These polymers contained a large amount of nitrogen residues in the form of amine, amide, and amine oxide groups. Their concentration varied with the composition of the starting TMS/NH3 mixtures. The mixing of NH3 gas with TMS influenced the chemical state of Si residues and accelerated the oxidation of Si atoms to form silicon oxides such as SiO, Si2O3, and SiO2. The polymers formed by glow discharge polymerization in the TMS/NH3 mixtures were combinations of Si- and N-containing polymers and silicon oxides.
