The results of microstructure effect on corrosion-mechanical endurance 1.2 mm thick alloy Al-Mg-Si-Cu alloying system and its welded joints, depending their condition due to different types HT are presented. Change the joints during performance various operations practically does not affect resistance against intergranular exfoliating corrosion. Effect joint under conditions simultaneous action...

The inhibitive effect of compound (1-acetyl-4, 5-dihydro-5-Bromophenyl-3-(thiophen-2yl) pyrazoles) on mild steel in 1M H2SO4 and 1M HCl was investigated by weight loss, Potentiodynamic polarization and electro chemical impidence studies. The synthesized compound of 1-acetyl-4, 5-dihydro-5-Bromophenyl-3-(thiophen-2yl) pyrazoles was characterized by FTIR, H NMR, C NMR and mass. The purity of the ...

S. Krum, F. Pešlová, Czech Technical University in Prague, Faculty of Mechanical Engineering Prague, Czech Republic, J. Kliber VŠB TU Ostrava, Czech Republic Corrosion resistant steels are used for the prod uction of parts exposed to corrosive environment and also to thermo-mechanical loads. Steel molds in the glass manufacture industry with their functional surfaces simultaneously exposed to t...

OBJECTIVE The authors reported the feasibility and safety of thoracoscopic approach for resection of the esophagus in two patients with diffuse corrosive esophageal stricture. BACKGROUND The unrelenting corrosive strictures of esophagus merit esophageal substitution. Because of the risk of complications in the retained esophagus, such as malignancy, mucocele, gastroesophageal reflux, and blee...

Accidentally ingested corrosive substances can cause functional and structural damage to the esophageal tissue resulting in stricture formation. It has been reported that the administration of olmesartan (OLM) can have anti-inflammatory, antifibrotic and antiapoptotic effects on injured tissue. The aim of our study was to check if OLM could prevent formation of scars in the corrosive esophageal...

The wind turbine foundation serves as a permanent construction in the harsh marine corrosive environment, its anticorrosion design is essential to the safe use of the wind turbine structure. At present, there is a significant controversy over the local corrosion mechanism (such as pitting corrosion, and crevice corrosion) and its diffusion mechanism in the academic circle. In the paper, the Far...

The hydrogen uptake of five carbon steel wires exposed to a corrosive CO2/H2S environment where protective film formation was not favorable measured. uptakes decreased with the accumulation retained carbide for most materials. It is assumed that adsorbed on carbides at some distance from ferrite will easily diffuse steel, hence giving beneficial effect. This effect observed material lowest cont...

The problem of corrosive destruction concrete and reinforced structures industrial buildings affected by aggressive environments does not lose its relevance, because, despite the abundance modern methods protection, there are still no radical corrosion control. Corrosive building materials leads to a strength load-bearing capacity reduction, loss aesthetic properties and, consequently, decrease...

In this series, six patients had periodic oesophageal dilatation with relief of symptoms. Two patients had feeding gastrostomies. Definitive surgical procedures were performed in 32 patients of which nine had oesophageal bypass, and 23 oesophageal resection with a visceral replacement. The colon was used in eight oesophageal bypass procedures and the jejunum in two. One patient who had a coloni...

We report a 24-year-old woman with corrosive poisoning who was subjected to pertechnetate scintigraphy to evaluate gastric injury. Fusion imaging (SPECT-CT) provided valuable information regarding viability of gastric mucosa, and it helped guide appropriate management.
