In this work, cobalt-doped Cadmium oxide thin films are prepared by sol-gel spin coating technique on the glass substrate. The effects of annealing temperature and Co concentration on Structural, optical properties of the thin films are studied. XRD pattern indicates that a CdO single phase with a cubic polycrystalline structure is formed in all the samples. Prepared thin film samples were revealed by EDX analysis. Optical measurements show that the optical transmission of the layer is reduced and the optical-band gap decreases due to the increase in molar concentrations. The optical-band gap is decreasing while increasing of Co concentration and annealing temperature.
Electrodeposition technique provides an easy way to produce magnetic thin films. Magnetic thin films are extensively used in various magnetic induction writing heads, magnetic MEMS devices and other magnetic sensing devices. Thus we have synthesized CoMnP thin films from aqueous bath with organic additive saccharin using electrochemical deposition technique and examined its magnetic properties. The electrochemical deposition method is especially interesting due to its low cost, high throughput and high quality of deposit. The CoMnP alloys were electrodeposited galvanostatically for various composition of the bath solution and for various concentration of the additive saccharin. The effects of electrodeposition condition and organic additive saccharin on the magnetic properties of CoMnP thin films were investigated. Structure and the Morphology of the film were studied using X-Ray diffractometer (XRD) and scanning electron microscopy (SEM). Elemental compositions of the film were studied using energy dispersive X-Ray Spectroscopy (EDS). Magnetic properties of the deposited films were studied using Vibrating sample Magnetometer (VSM). SEM measurement indicated that the surface morphology was affected by the nature of the organic additives to a large extent. CoMnP films formed under optimized conditions are found to be polycrystalline in nature with hcp structure. Moreover, it was obvious that the presence of organic additive saccharin, in the electroplating bath, modified the magnetic properties of the CoMnP thin films according to the VSM measurements.
Mixed-mode delamination crack growth characteristics in a SiC/SiC woven laminated ceramic matrix composite is analyzed. Delamination crack growth under mixed mode conditions was investigated using a computational mechanics approach. For the purpose of this study the CMC specimen considered was in 4-point bending. A notch, of 1/3 of the specimen width was considered in the analysis. In this paper only symmetric delamination crack growth were investigated and results presented. Effects of other parameters, such as loading configuration, material properties, crack configuration, and effect of temperature on the energy release rates were also investigated.
