The corrosion behaviour of AZ31 magnesium alloy with different grain sizes immersed in simulated body fluids was compared in chloride solution (8 gl(-1)) and in phosphate-buffer solution (PBS). The influence of immersion time was also analyzed. Electrochemical techniques such as open circuit potential, polarization curves, transient currents and electrochemical impedance spectroscopy, complemen...

The electrochemical corrosion behaviour of mild steel embedded in concrete, and partially immersed in 0.2M H2SO4, was studied in this investigation at ambient temperature by potential monitoring technique. The experimental work was performed with a digital multimeter and a Cu/CuSO4 electrode (CSE) as the reference electrode. Extracts of carica papaya leaves and sodium nitrite (NaNO2) in differe...

in this study, mixed metal oxides al2o3/mgo/tio2 coatings with al/mg/ti ratio of 5:1:3 and 2.5:3:4 were coated on aluminum by sol-gel method. the surface morphology, phase analysis, thermal behavior and the corrosion behavior of the al2o3/mgo/tio2 coatings were characterized by (sem), (xrd), (tg-dta) and potentiodynamic polarization test in 3.5 wt.% nacl solution. the results demonstrated that ...

In this paper , the effect of curing time and temperature as well as various primers on durability of high density polyethylene on plain carbon steel have been investigated. The aim is to increase adhesion, improve durability and also to produce a defect-free in order to improve the corrosion resistance of steel substrate. For this purpose, after surface preparation and applying a primer (zin...

Metallic coatings using thermal spraying techniques are widely applied to structural steels to protect infrastructure against corrosion and improve durability of the associated structures for longer service life. The thermal sprayed metallic coatings consisting of various metals, although have higher corrosion resistance, will still corrode in a long run and may also subject to corrosion induce...

Nickel based alloys have been developed as materials offering superior corrosion fatigue. The fatigue performance of IN600, IN601 and C22 was examined in increasing saline solution severity of 3.5% sodium chloride at pH = 6.8. Results of fatigue and corrosion fatigue tests indicate that the fatigue lives of IN600, IN601 and C22 tested in 3.5 % sodium chloride solution (NaCl) are essentially the...

Aluminum and aluminum alloys can be protected against corrosion by various methods of surface modification (e.g., metal finishing, anodizing, chromate conversion coatings, metallic cladding with Alclad, corrosion protection compounds, and solution phase inhibitors). The desire to deploy environmentally compliant multi-functional coatings has created the need for new concepts that can protect Al...
