    Ar+-induced mixing mechanisms in metal-metal bilayer systems (1992)
    Springer
    Journal of materials science 27 (1992), S. 2141-2146

    Notes: Abstract Ion-beam mixing in Al-Pd, Al-Cr, Pd-Cu, Ag-Cu and Ag-Fe bilayers has been studied using Rutherford backscattering spectroscopy (RBS) and Auger electron spectroscopy (AES) over an ion dose range between 1 × 1015 and 1 × 1016 Ar+ cm−2 at room temperature. RBS and AES results show that the mixing efficiency of the light elements is higher than that of the heavy elements. The mixing efficiency of a heavy element is independent of the heat of mixing energy, while that of a light element has a close relation with the heat of mixing. The experimental results are discussed in terms of cascade mixing and thermal spike mixing.

    Transverse dimensions of wood pulp fibres by confocal laser scanning microscopy and image analysis (1992)
    Springer
    Journal of materials science 27 (1992), S. 6391-6400

    Notes: Abstract Cross-sectional images of wood-pulp fibres were generated using optical sectioning by a confocal laser scanning microscope. The technique has a distinct advantage over mechanical sectioning with a microtome, as it simplifies specimen preparation. Cross-sectional images were obtained for unbleached softwood kraft pulp fibres using epifluorescence mode. The accuracy of cross-sectional images was verified by imaging fluorescent microspheres. An image analysis procedure, in which the boundaries of fibre cross-sections were defined with a maximum-gradient edge-finding technique, was developed for measuring fibre cross-sectional area and wall thickness rapidly and accurately. The measurements were insensitive to the confocal microscope's asymmetric resolution, signal deterioration through the specimen thickness, overall image quality and operator bias.

    Lyotropic effect in surface charge, electrokinetics, and coagulation of a rutile dispersion (1994)

    Notes: Abstract Potentiometric, electrokinetic, and coagulation experiments with a rutile dispersion in the pH region above the point of zero charge exhibit an “inverse” lyotropic sequence for counterions: Li+〉K+〉Cs+. The potentiometric and electrokinetic data were interpreted by a surface complexation model assuming the Stern-Gouy-Chapman structure of the interfacial layer, which yielded the values of inner layer capacitances,C, and the intrinsic equilibrium constants,K ass 0 , characterizing the specificity of each counterion. These parameters were used to explain the order of lyotropic sequences in the adsorption, coagulation, and electrokinetic phenomena.

    Mechanism of adhesion improvement in ion-beam mixed Cu/SiO2 (1994)
    Springer
    Journal of materials science 29 (1994), S. 749-753 
    Details
    ISSN: 1573-4803
    Source: Springer Online Journal Archives 1860-2000
    Topics: Mechanical Engineering, Materials Science, Production Engineering, Mining and Metallurgy, Traffic Engineering, Precision Mechanics
    Notes: Abstract A thin copper layer (35 nm) deposited on SiO2 has been subjected to ion-beam mixing with 80 keV Ar+ at room temperature, 550 and 650 K. Interfacial properties of irradiated samples were investigated using Rutherford backscattering spectroscopy, grazing-angle X-ray diffraction, X-ray photo-electron spectroscopy and scratch testing. The adhesion of the copper film was improved by a factor of three at a dose of 1.5 × 1016 Ar+ cm−2 by the ion-beam mixing at room temperature, while the high-temperature ion-beam mixing enhanced the adhesion by a factor of five. Ballistic mixing plays a role in the improvement of adhesion for the room-temperature ion mixing, and the creation of Cu2O phase induced by ion-beam mixing contributes to the enhancement of adhesion at high temperature.
