This paper investigated the effectiveness of anticorrosive protection of a number of metals by means of compositions based on petroleum oils modified with the Cortec VpCI-369 composition (Cortec Corporation, USA). The work of adhesion of the studied compositions and their wetting with water were determined. The contributions of individual components of the protective system to the total effectiveness in a chloride solution are estimated using the method of polarization resistance. Oil compositions with Cortec VpCI-369 (3-10 wt.%) show high protective efficiency when applied to structural carbon steel tested in a thermal moisture chamber (98-100%) and under normal conditions (86-96%). In a chloride-containing neutral solution with an exposure time of 456 h, these compositions are effective against the effect of copper and brass.
