摘要

Adding corrosion inhibitor in corrosive medium is one of the effective methods to solve the corrosion of steel materials. In recent years, corrosion inhibitors of plant extracts have become a research hotspot. However, there are few studies on the corrosion inhibitors of algae extract. It is of great theoretical and practical application value to study the corrosion inhibition performance of algae extract. In this work, with algae as the raw material of corrosion inhibitor, the effects of different concentrations of algae extract on the corrosion behavior of Q235 steel were studied by means of self-corrosion potential time curve and polarization curve. The effective corrosion inhibition components of algae extracts were preliminarily determined by Fourier transform infrared spectroscopy. The corrosion morphology of Q235 steel in hydrochloric acid solution with or without corrosion inhibitor was characterized by scanning electron microscope.
