In the oxidation of metals and alloys, microstructural features at the atomic level play an important role in the nucleation and growth of the oxide, but little is known about the atomic mechanisms of high temperature oxidation. The present paper describes current progress on crystallographic aspects of aluminum oxidation. The 99.999% pure, polycrystalline aluminum was chemically polished and oxidized in 1 atm air at either 550°C or 600°C for times from 0.5 hr to 4 weeks. Cross-sectional specimens were prepared by forming a sandwich with epoxy, followed by mechanical polishing and then argon ion milling. High resolution images were recorded in a <110>oxide zone-axis orientation with a JE0L JEM 200CX microscope operated at 200 keV.

AbstractEffects of ion-irradiation on oxidation of silicon at low temperatures (130°C) in an argon and oxygen mixed plasma excited by electron cyclotron resonance (ECR) interaction are investigated. First, dependence of energy and flux of incident ions on the flow rate and the microwave power is evaluated. It is shown that the flow rate and the microwave power are key parameters for controlling the energy and the flux of incident ions, respectively. Second, growth kinetics of the oxide films are studied. The growth rate depends on the energy and the flux of argon ions irradiated to the substrate, and the growth thickness increases proportionally to the root square of the oxidation time. Thus, the growth rate is limited by diffusion of oxidants enhanced by irradiation with argon ions. The effect of substrate bias on oxidation characteristics is also discussed. The electrical properties of the oxide films are improved by increasing the bias. The improvement is due to the reduction of damage at the surface of the substrate induced by the irradiation.

In this work, PVA/Ag nanocomposites films were prepared using solution casting technique, these films were irradiated with Argon ion beam to modify the structure. The main objective of the study is to enhance the optical and electrical properties of the polymer nanocomposites films by irradiation. The conventional characterization techniques such as UV–Visible spectroscopy, X-ray diffraction (XRD), Fourier transform infrared (FTIR), transmission electron microscope (TEM) and dielectric measurement are employed to understand the structure–property relations. FTIR analysis of these composite films shows chemical changes and a significant impact on them can be observed after irradiation. After doping, the XRD data shows silver nanoparticles formation in the PVA polymer. The band gap energy of samples is decreased with increases in the concentration of silver nanoparticles and ion beam fluence, which gives clear indication that ion beam irradiation induced defects are formed in the composite systems. The electrical conductivity, dielectric loss [Formula: see text] and dielectric constant [Formula: see text] are increased with increasing ion beam fluence and Ag dopant concentration.
