[Effect of sulfate-reducing bacteria on steel corrosion in the presence of inhibitors].
Steel 08KP corrosion was studied as affected by inhibitors in presence of sulphate-reducing bacteria (SRB). Organic compounds, containing functional groups with nitrogen, oxygen and sulphur atoms, were investigated as corrosion inhibitors. It is shown that the studied inhibitors may be divided into three groups as to the mechanism of protective action. It has been established that cation-active nitrogen-containing surfactants ([symbol: see text] X, [symbol: see text]-1, [symbol: see text]-1M, catapin M, [symbol: see text]-2M) are the most efficient steel corrosion inhibitors. Such inhibitors, when adsorbed on metal surface, can affect the process of hydrogen precipitation on its surface, and thus inhibit catalytic function of SRB as the depolarizer of cathode process.
