Lithium carbonate and lithium oxalate were incorporated as leachable corrosion inhibitors in model organic coatings for the protection of AA2024-T3. The coated samples were artificially damaged with a scribe. It was found that the lithium-salts are able to leach from the organic coating and form a protective layer in the scribe on AA2024-T3 under neutral salt spray conditions. The present paper...

The effects of shot-peen forming on the fatigue properties aluminum alloy samples were measured with a mechanical testing & simulation (MTS) tester in atmospheric and salt-spray environments. After forming, performance sheet was significantly improved both salt spray environment. Compared detail rating (DFR) value environment, DFR original decreased to 110.82 MPa, decreasing by 4.47%. shot-...

The effects of wollastonite nanofibers on the physical and mechanical properties of particleboard were studied. Nano-wollastonite (NW), with the size range of 30 to 110 nm, was applied at 5, 10, 15, and 20%, based on the dry weight of wood chips, and compared with control specimens. Two application methods of NW were used: surface application (SA) and internal application (IA). Density was kept...

OBJECTIVES The objective of this work was to spray dry p-aminosalicylic acid (PAS) and its ammonium salt and to investigate the impact of the pore-forming agent, ammonium carbonate (AC), on the morphological, aerodynamic and physicochemical properties of the resulting powders. METHODS Microparticles were prepared by spray drying from ethanol/water solvent systems. Their solid-state properties...

Here we report a novel approach for preparation of a 6-day transdermal drug delivery system (TDDS) as treatment for mild to moderate Alzheimer’s disease. The spray drying method was used to prepare microparticles containing the anti-Alzheimer drug. The content of the drug was determined by High Performance Liquid Chromatography (HPLC) method. The morphology and size range of the microparticles ...

Biogenic influences on the composition and characteristics of aerosol were investigated on Bird Island (5400 S, 3803 W) in the South Atlantic during November and December 2010. This remote marine environment is characterised by large seabird and seal colonies. The chemical composition of the submicron particles, measured by an aerosol mass spectrometer (AMS), was 21 % non-sea-salt sulfate, 2 % ...

Anticorrosion protection on the basis of water-thinnable paint systems belongs among one of ecological ways of protection of metal parts. The aim of the experiment was to test corrosion resistance of water-thinnable systems Eternal antikor speciál V9503 and Colorlak aquarex V2115 in the salt spray environment according to the norm ČSN ISO 9227. Ductility of used paint systems in complience with...
