Cerium conversion coatings are a potential alternative to chromium conversion coatings for improving the corrosion resistance of magnesium alloys. This study detailed the microstructure and corrosion resistance of cerium conversion coatings on AZ31 magnesium plates treated in 0.05 kmolm 3 cerium nitrate solution, with and without 0.25 kmolm 3 hydrogen peroxide. The results indicate that the cor...

In this work, poly (ether-block-amide) (PEBA)/ceramic hollow fiber (HF) composite membranes with high flux were prepared by dip-coating the ceramic hollow fiber with PEBA polymer solution for pervaporation (PV). The membrane fabrication was optimized by finely tailoring the coating parameters such as the viscosity and concentration of PEBA coating solution, which made the pervaporation flux as ...

In order to improve the corrosion and wear resistance of biomedical Ti-6Al-4V implants, a Ta₂N nanoceramic coating was synthesized on a Ti-6Al-4V substrate by the double glow discharge plasma process. The Ta₂N coating, composed of fine nanocrystals, with an average grain size of 12.8 nm, improved the surface hardness of Ti-6Al-4V and showed good contact damage tolerance and good adhesion streng...

Poultry meat is a susceptible product for growth of spoilage and pathogenic microorganisms. The shelf life extension of raw poultry meat is a challenge in food industry. In this research, the combined effect of dipping in a carboxymethyl cellulose (CMC) solution containing black pepper seed (Piper Nigrum) extract (BPE) and turmeric (Curcuma Longa L.) extract (TE) (2% ...

We outline the ability of zinc phosphate coatings, obtained by chemical conversion, to protect mild steel rebars against localized corrosion, generated by chloride ions in alkaline media. The corrosion resistance of coated steel, in comparison with uncoated rebars and coated and uncoated steel rebars embedded in mortar, were evaluated by open-circuit potential, potentiodynamic polarization, cro...

___________________________________ April 4, 2002 National Organic Standards Board Technical Advisory Panel Review Page 1 of 1 Compiled by OMRI for the USDA National Organic Program Executive Summary Potassium sorbate was petitioned for use as a preservative for an unspecified seed film coating. The reviewers were unable to fully evaluate the petition since the specific polymer was not identifi...

the idea of smart corrosion inhibition is basis on either inhibitor consumption where it is needed or reducing harmful matrix interaction with it. in addition, applying corrosion inhibitor in a coating causes many problems such as loss of inhibition capability, coating degradation, or both. a useful technique to overcome this problem is applying of inert host systems of nanometer dimensions as ...
