Abstract

The experiment was carried out in the acidic conditions to test three kinds of organic compounds, the cetyltrimethyl ammonium bromide (CTAB), nicotinic acid and bromohexadecyl pyridine on the corrosion inhibition performance of metal Zinc by means of the experiment and testing methods of the static rotary coupon test, electrochemical polarization and SEM (Scanning Electron Microscope). The purpose is to study a kind of compound organic corrosion inhibitor which has the best inhibition effects on the metal Zinc. The static coupon experiment showed that the weight loss ratio of metal Zinc specimens was relatively small in CTAB and bromohexadecyl pyridine composition and the weight loss ratio of metal Zinc specimens was relatively large in the nicotinic acid composition. The electrochemical polarization test result showed that CTAB, nicotinic acid and bromohexadecyl pyridine can induce the shifting of the corrosion potential of metal Zinc (E0) in the acidic environment. SEM showed that CTAB and bromohexadecyl pyridine composition formed a uniform and compact film on the metal Zinc surface. The conclusion can be drawn that CTAB, nicotinic acid and bromohexadecyl pyridine can be combined with one another in the acidic conditions. Among them, the CTAB and bromohexadecyl pyridine composition has a good inhibition effect on the corrosion of metal Zinc in that it forms a uniform and compact film on the surface of metal Zinc.
