  text: 'Interfacial reactions at the polycarbonate (PC)/FeCr-alloy interface during
    melt contact were studied as function of the Fe:Cr ratio within the alloy. Thin
    Fe/Cr films with lateral composition gradients were deposited by magnetron sputtering;
    the analysis of the films was done with microscopy and X-ray photoelectron spectroscopy
    (XPS). The local interfacial polymeric film formation could be therefore directly
    correlated with the Fe:Cr ratio. The local thickness and structure of the formed
    polycarbonate residue was analyzed by means of imaging ellipsometry, atomic force
    microscopy as well as Fourier-transform infrared spectroscopy under grazing incidence
    and XPS. Moreover, confocal fluorescence microscopy of the PC melt/alloy interface
    could reveal the formation of minor degradation products in the interphase region.
    The results show that already an Fe:Cr ratio of 2 : 1 leads to a strong inhibition
    of the thermal degradation in comparison to the unalloyed iron, and that in general,
    the enrichment of chromium in the passive film leads to an effective suppression
    of interfacial PC degradation. The data contributes to improving the mechanistic
    understanding of the role of iron during this process. Additionally, a critical
    concentration of chromium in the alloys used for PC processing can be deduced.'

    plasma deposited films on the corrosion resistance of adhesive films on a laser
    surface melted 7075 aluminium alloy was investigated by means of complementary
    techniques in comparison to the just laser surface melted state. Laser surface
    melting (LSM) was performed using a continuous wave mode at a wavelength of 1064 nm.
    Ultra-thin plasma polymer films were deposited from a mixture of hexamethyldisilane
    (HMDSO), oxygen, and argon by means of an audio-frequency glow discharge. The
    surface morphology and surface chemistry compositions were investigated by employing
    field emission scanning electron microscopy, energy-dispersive X-ray spectroscopy
    (EDX), diffuse reflection infrared Fourier transform spectroscopy, and X-ray photoelectron
    spectroscopy. The corrosion resistance of plasma polymer coated LSM Al-7075 alloy
    was studied using linear sweep voltammetry and electrochemical impedance spectroscopy
    in a chloride-containing electrolyte. The electrochemical studies showed an improved
    corrosion resistance for plasma film-coated alloys compared to the just laser
    surface melted state. To study the corresponding surface adhesive properties,
    the samples were coated with an epoxy amine adhesive. 90°-peel test under humid
    conditions confirmed the improvement of interfacial wet-adhesion corrosion tests
    showed a strong improvement of the delamination resistance of adhesives caused
    by the ultra-thin interfacial SiO<jats:sub>x</jats:sub>-films.</jats:p>
