Compound of Green Volatile Corrosion Inhibitor and Its Corrosion Inhibition Performance

The work aims to compound a green composite volatile corrosion inhibitor and explore its corrosion inhibition effect on carbon steel and brass metal samples in order to solve the problem of poor corrosion inhibition performance of one-component green volatile corrosion inhibitor. The corrosion inhibition effect and film forming durability of composite volatile phase corrosion inhibitor on carbon steel and brass were tested and analyzed by corrosion weight loss, contact angle and electrochemical tests. The corrosion inhibition efficiency of the composite volatile corrosion inhibitor for No. 10 steel and H62 brass was 84.71% and 91.67% respectively, and the corrosion inhibition performance was significantly better than that of the single-component volatile corrosion inhibitor. The composite volatile corrosion inhibitor formed a corrosion inhibitor film on the surface of No. 10 steel and H62 brass, and the corrosion inhibitor film formed on the surface of H62 brass was more durable than that of No. 10 steel. Compared with single-component volatile corrosion inhibitor, the composite volatile corrosion inhibitor has good corrosion inhibition effect on carbon steel and brass, providing support for the application of green volatile corrosion inhibitor in antirust packaging.
