Abstract Composite coatings were prepared by using epoxy-hardener having a 2:1 composition and functionalized SiO 2 0, 0.01, 0.03, 0.05 proportion/s accordingly. Curing of the on aluminium alloy 7075 substrates was performed at temperature 60 ± 5 °C. Moreover, corrosion assessment carried out in 0.6M NaCl solution room temperature. The outcome Fourier Transform Infrared Spectroscopy (FT-IR) con...

In recent year’s aluminum and aluminum alloys are widely used in automotive industries. These are light weight (density of about 2.7g/cc),having good malleability and formability, high corrosion resistance and high electrical and thermal conductivity. High machinability and workability of aluminum alloys are prone to porosity due to gases dissolved during melting processes. However, in the engi...

Abstract The shape of the projectile seems to determine effect a ballistic impact and failure mechanism. In this study, numerical analysis with different shapes, i.e ., ogive, blunt, conical, hemispherical is performed. target circular sandwich plate an outer diameter 315 mm, which composed three layers thickness 1 mm for each layer. These will be filled materials such as 1100-H12 aluminum allo...

Al86Ni8Co1La1Y2Gd2 amorphous coatings were prepared using cold gas kinetic spray technology. The results show that are achieved with the porosity about 3.2%, thickness 893 ?m, amount of phase 82.5%, hardness 300HV0.2. corrosion potential and anti-corrosion life 7075 T6 alloy aluminum ?0.78 V 72 h, respectively. electrochemical analysis neutral salt ?0.69 274 h for Al-based coatings, Therefore, ...

2014 A summary is given of data obtained from neutron diffraction experiments on heavy water at elevated pressures and temperatures using three different types of pressure vessel. The pressure vessels were manufactured from (i) hard steel (EN24T), (ii) titanium-zirconium null alloy, and (iii) autofrettaged aluminium alloy (7075-T6). In cases (i) and (ii), hydraulic pressures up to 6 kbar were a...

In this study, the effect of temperature on the diffusion welding of AZ31 magnesium alloy and 7075 aluminum was discussed. Diffusion welding temperature was the most important parameter since all mechanisms are sensitive to temperature in Diffusion welding method. Intrusive contacts between the two alloys at temperatures of 430, and 440 °C 450 and took 60 min. In all tests constant pressure and...

The present study was undertaken to investigate the effect of aging parameters (time and temperature) on the mechanical properties of Be-and/or Zrtreated Al-Mg-Zn (7075) alloys. Ultimate tensile strength, 0.5% offset yield strength and % elongation measurements were carried out on specimens prepared from cast and heat treated 7075 alloys containing Be and/or Zr. Different aging treatment were c...
