Preparation of TiO2 Coatings on Carbon Fibers
Autor: Rida Gallyamova, Rustam Safiullin, Vladimir Dokichev, Fanil F. Musin
Publikováno v: Materials Science Forum. 1049:117-123
Carbon fibers have been TiO2 coated. Previously, the carbon fiber surface has been heat-treated to remove the sizing. The TiO2 layer has been formed on the fiber surface using the sol-gel technique by immersion in a solution. After coating, the sampl

Influence of the electromagnetic field on the corrosion of low-carbon steel in aqueous mineralized media and on the crystallization of calcium carbonate in the presence of iron(II) ions
Autor: Vladimir Dokichev, Alexander Voloshin
Publikováno v: SOCAR Proceedings. :116-124
The influence of the electromagnetic field (EMF) on the corrosion of structural carbon steel in a 3% aqueous solution of sodium chloride in the presence of CO2 was studied. It is shown that the EMF increases the corrosion rate of steel by 1.13 times

New «green» inhibitors of gas hydrate formation for the oil and gas industry based on polysaccharides
Autor: Vladimir Dokichev, Alexander Voloshin
Publikováno v: SOCAR Proceedings. :33-40
The thermobaric conditions for the formation of gas hydrates in the presence of the sodium salt of carboxymethylcellulose, dextran, and arabinogalactan were studied in a quasi-equilibrium thermodynamic experiment. It is established that polysaccharid
