Potentiodynamic results of anodic behavior of Zn5Al and Zn55Al alloys, alloyed with Beryllium in the ambience of NaCl electrolyte and their microstructures are studied. They showed that a small addition of Beryllium (0.005 - 0.05 wt%) improves the corrosion resistance of Zn5Al and Zn55Al original alloys to 2 - 3 times by changing grains shape to spherical and changing sizes to small grains. The proposed composition of Zinc-Aluminum alloy, which contains of Beryllium, can be used as anodic coatings to protect steel products and constructions against corrosion. 展开更多

The results of anodic behavior of Zn5Al, Zn55Al alloys alloyed with Magnesium in the environment and their micro-structures are studied. A potentiodynamical research carried out by Zinc-Aluminum alloys, alloyed with Magnesium obtained a corrosion-resistant coating with optimum concentration of Magnesium about 0.005 - 0.1wt%. The rate of corrosion of these alloys is 2 - 2.5 times lower than Zn5Al, Zn55Al initial alloys. It is explained by the effect of modification on the structure of original alloys and they can be used as an anticorrosion coating for protecting corrosion of steel frames. 展开更多

Fat and wax (F&W) compounds have to be removed from raw plant materials before pectin and oligosaccharides (OS) can be isolated. In this research, the mixtures of F&W, and polyphenols and sugars were firstly separated from the roots of Eremurus hissaricus (Eremurus h.), and the byproducts of fruit processing, such as apple pomace, sunflower head residues, and grape seeds, etc., using hexane/ethanol or ethyl acetate as leaching reagents at various ratios of liquid to solid. The resultant mixtures were then extracted with an ethanol/water mixture to separate F&W from polyphenols and sugars. It was found that the F&W yield decreased in the sequence of apricot > apple > sunflower head residues > peach > pumpkin with 21.84% in apricot as the highest number. The amount of alcohol-water soluble compounds (AWSC), mainly polyphenols and sugars, decreased in the sequence of peach > sunflower head residues > apricot > pumpkin > apple. No inter-dependence of AWSC and F&W was identified. 展开更多
