Abstract / Full Text

Using the method of measuring ohmic resistance of steel AISI 304 specimens, the time dependence of steel corrosion rate in the 0.1–2 M HCl solutions is determined under the conditions of free air access. In the 0.5 M HCl solution, the effect of thiourea and polyethylene polyamine inhibitors on the steel AISI 304 corrosion rate is studied. It is shown that the inhibitory effect of thiourea on the corrosion rate of AISI 304 steel depends on the time of steel exposure to the solution.
