Abstract In this work, zinc chloride (ZnCl₂), potassium sodium tartrate (PST) and tributyl phosphate (TBP) were compounded into a ternary antioxidant corrosion inhibitor ZPT, meanwhile, the corrosion resistance of A3 steel in simulated mineralized water and the corrosion inhibition mechanism of ZPT were investigated by static weightlessness, electrochemical method and surface analysis method. The corrosion rate of A3 steel was reduced from 0.239 3 mm/a to 0.031 8 mm/a with a corrosion inhibition rate of 86.71% by adding 900 mg/L ZPT to the simulated mi-neralized water with a dissolved oxygen concentration of 7.31 mg/L. The corrosion resistance of A3 steel in simulated mineralized water was also investigated by static gravimetry and electrochemical and surface analysis tests. When the pH value of the solution is 7—9, the corrosion inhibitor has a high corrosion inhibition rate, while it’s corrosion inhibition performance decreases in a strong acid and alkali environment. Electrochemical tests showed that impedance increased with the increase of ZPT concentration, and the corrosion inhibitor mainly inhibited the cathodic reaction. When the mass fraction of ZPT was 900 mg/L, the capacitive arc radius was the largest, the self-corrosion current density was the smallest, and the slope of the cathodic portion of the curve was the largest. After adding corrosion inhibitor, the surface of steel plate became flat and smooth, and the corrosion depth was reduced. The metal surface film consisted of TBP-Zn²⁺, PST-Zn²⁺ coordination compound, Zn(OH)₂ precipitation film and iron oxide. With the addition of ZPT, Zn²⁺ will react with phosphate and tartaric acid in TBP and PST to form TBP-Zn²⁺ and PST-Zn²⁺ coordination compounds, and also react with OH^- generated by the cathode to form Zn(OH)₂ precipitation film, these three are complementary to each other on the metal surface to make the protective film more dense and complete, and iron oxides will be generated in the area where is not be covered by corrosion inhibitor’s protective film.
