AbstractThe surface film on pure magnesium and two aluminium-containing magnesium alloys was characterised after 96 h at 95% RH and 22 °C. The concentration of CO2 was carefully controlled to be either 0 or 400 ppm. The exposed samples were investigated using X-ray photoelectron spectroscopy, Fourier transform infrared spectroscopy, X-ray diffraction, and electron microscopy. The results showed that when the alloys were exposed to the CO2-containing environment, aluminium cations (Al3+) was incorporated into a layered surface film comprising a partially “hydrated” MgO layer followed by Mg(OH)2, and magnesium hydroxy carbonates. The results indicated that aluminium-containing magnesium alloys exhibited considerably less localised corrosion in humid air than pure magnesium. Localised corrosion in the materials under investigation was attributed to film thinning by a dissolution/precipitation mechanism.

Short And Long Term

Grass carp were exposed to two therapeutic concentrations of copper sulfate (10 mgxL-1 in 1 hour and 1 mgxL-1 in 24 hours). Twenty-four hours after the copper sulfate baths, the histopathology of the gills was studied. The observed lesions in gills after short and long term baths were: mucus coagulation and accumulation of cellular debris on the epithelium of lamellae and inter lamellar regions, lamellar edema, hemorrhage, hyperplasia, epithelial cell necrosis, congestion and aneurysm (telangiectasis) in the secondary lamellae. In the 24 hour copper sulfate bath, the percentage of gill lesions that were observed correlated directly with the copper sulfate concentration (p0.05). Epithelial necrosis (89% in 10 mgxL-1 for 1 h) was the most prevalent lesion in these groups.
