Nowadays, 80–90% of the components airplanes are composed aluminum alloys. Another material with a high level corrosion resistance and is utilized in aircraft AA5052. When exposed to natural environment, AA5052 forms an oxide layer that shields alloy from corrosion. However, this eroded corrodes more quickly harsh weather conditions where aeroplane operates. On substrate, multilayered nanostruc...

Carboxymethyl cellulose (CMC)/titanium dioxide (TiO2) was prepared using gamma irradiation at different doses. used as a matrix and TiO2 in contents added (0.25, 0.5, 1, 1.5 wt%) filler. The polymer composite films were irradiated doses of 5, 10 15 kGy 60Co γ-ray to form crosslinked network structure. described by diagnostic procedures including X-ray diffractometer, scanning electron microscop...

Abstract This study investigated the production of silicon from bamboo leaves to solve challenge in solar market using Optimization approach. The effect three independent variables of: temperature, time and amount were studied Box Behnken design. best process level observed Benhken Design optimal predicted used produce silica. It was then subjected X-Ray Diffractometer determine most reactive s...

In this paper, electrodeposition and visible light photocurrent responses of Zn-doped Cu2O were reported. The process was conducted with different deposition time to study the growth deposit. structural investigation elemental analysis performed on an energy dispersive X-ray spectrometer diffractometer, respectively. crystal studied from micrograph obtained using a field emission scanning elect...

In this study, Ni50Ti50 powder was coated on the surface of graphite substrate (C) via a plasma spraying process using radio frequency inductively coupled reactor. The coating carried out 12- and 9-kW power under Ar atmosphere. cross-section layers were examined with Scanning Electron Microscope (SEM), Energy Dispersive X-ray Spectrum (EDX), Diffractometer (XRD) analyses microhardness test. thi...

Ultrasonic burnishing is one of several surface treatment methods. The method a relatively new process used for finishing workpieces to produce good quality. This paper presents ultrasonic as mechanical improving the quality planar plates. improves by increasing hardness workpiece and reducing its roughness. However, it essential know effect on residual stresses in material. study investigated ...

A series of mesoporous catalysts (MCM-41) promoted by copper oxide nanoparticles were prepared by the co-precipitation method and tested for the decomposition of carbon tetrafluoride (CF4). The addition of copper oxide nanoparticles to MCM-41 led to an improvement in the catalytic activity for CF4 decomposition. The catalyst was the most active around 5 wt% copper oxide added to MCM-41. Methods...

BiVO₄/Mn1-xZnxFe₂O₄ was prepared by the impregnation roasting method. XRD (X-ray Diffractometer) tests showed that the prepared BiVO₄ is monoclinic crystal, and the introduction of Mn1-xZnxFe₂O₄ does not change the crystal structure of BiVO₄. The introduction of a soft-magnetic material, Mn1-xZnxFe₂O₄, was beneficial to the composite photocatalyst's separation from the liquid solution using an ...
