“…On the other hand, X-ray diffraction is considered a suitable method for checking the crystalline/amorphous nature of thin films, especially if the scanning rate is a continuous and slow. Moreover X-ray diffractograms give good and sufficient information about the nature of forming thin films rather than it is a low cost, fast, easy method and a very reliable technique [27][28][29]. This communication is a continuation of previous research works where authors studied nanostructure, optical and electrical properties of thermally evaporated CdS 0.1 Se 0.9 polycrystalline thin films with different thickness in one article [24] and in another work they studied the microstructure and crystalline imperfections of the ternary chalcogenide systems of CdS X Se 1−X thin films with compositions where 0.0≤x≤0.4 [27].…”

“…The XRD analysis results indicated that the Ni -(cubic ZrO 2 ) phases of nanocomposite coating are crystalline structures. Table 2 shows the crystallite size of nanocomposite coating is calculated for pure Ni matrix coating compared with Ni-ZrO 2 nanocomposite coating grains of stainless steel 316L substrate at a different weight percentage of nanoparticles utilized Debye-Scherrer's equation, given by [10].…”

This work aims preparation of Ni-based nanocomposite coating by electroless deposition method onto stainless steel (316L) substrate, the present work will compare the effects of incorporation of ZrO2 nanoparticles at different percentages (1.25 wt %, 2.25 wt %, and 4.25 wt %) Ni-based electroless deposition coating of the bath nanocomposite on the phase structure, microhardness, and corrosion resistance is studied. Where the structure and chemical composition of nanocomposite coatings were studied by using (X-ray), (SEM) and (EDS). of Ni - ZrO2 nanocomposite coating exhibits much-increased microhardness and remarkably improved corrosion resistance.

“…Under the action of an electric field, addition of Al 2 O 3 will increase the leakage current density of the composite ceramics, because Al 2 O 3 forms a liquid phase at grain boundaries between the ferroelectric and ferromagnetic phases during the sintering process, causing some carriers to concentrate at the grain boundaries. 47 Under the action of an external electric field, these carriers will move directionally, resulting in an increase in the leakage current. When the Al 2 O 3 content was 3%, the leakage current was the largest.…”

Magnetoelectric composites have attracted widespread attention during the past few decades due to their strong magnetoelectric coupling effect and potential applications above room temperature. Ni 0.5 Zn 0.5 Fe 2 O 4 /Ba 0.8 Sr 0.2-TiO 3 composites have been prepared by the conventional high-temperature solid-state method and the effects of Al 2 O 3 addition on their microstructure, dielectric, ferroelectric, and magnetic properties studied. x-Ray diffraction (XRD) analysis confirmed the biphase structure of the composites. scanning electron microscopy (SEM) showed that addition of a certain amount of Al 2 O 3 can enhance the density and promote uniform growth of particle size. The sample with 1 wt.% Al 2 O 3 addition exhibited the largest dielectric constant and lowest dielectric loss (< 0.05 at 1 kHz) at high temperature (> 354°C). The sample with 3 wt.% Al 2 O 3 addition presented the best ferroelectric properties, with the highest values of residual polarization (P r = 2.2150 lC/ cm 2 ) and coercive field (E c = 30.6527 kV/cm) among the specimens. The remanent magnetization (M r ) and saturated magnetization (M s ) decreased with increasing Al 2 O 3 content. In short, addition of Al 2 O 3 caused changes in the grain size, density, and defects, and addition of a certain amount of Al 2 O 3 can improve the magnetoelectric properties.
