Weight loss and electrochemical measurements at 30 u00b0C were investigated further, the inhibition of the varying concentration of APPH on the degradation of low steel in 0. 5 M H 2 SO 4 was investigated. After 6 hours of exposure, the percentage inhibition efficacy of APPH increased with increasing intensity, peaking to 84% at 0. 2 mM at 30 u00b0C. Further, the synergistic corrosion inhibition device APPH demonstrated that the inhibition effectiveness increases with increasing inhibitor concentrations, and that the maximum value was 83% at 0. 5 mM APPH.

In hypersaline seawater environments, a blend of nitrate-reducing prokaryotes and sulfate-reducing prokaryotes was investigated independently. Both microbial concordance and corrosion rates from Tafel extrapolation were roughly equal, but the maximum pit depth on the steel surface exposed to NRP-MIC was around 25% lower than that caused by SRP-MIC. SRP activity on the steel surface largely doubled the number of pits, resulting in more weight loss than NRP activity.

For 3 d and 8 d rotation tests respectively, a weight loss analysis revealed that B. cereus inoculum had anti-corrosion efficiencies of 92. 8 percent and 73. 8 percent. B. cereus inoculum was found in the amount of Fe 2 O 3 and increased the amount of CaCO 3 in corrosion products, according to a surface characterization report. B. cereus inoculum is the product of a chemical reaction that uses industrial cooling water anti-corrosion.

Using gravimetric and electrochemical tests, the effectiveness of phenyl phthalimide and its derivatives in inhibiting corrosion of carbon steel has been tested experimentally. However, experimental studies have not fully discussed the chemical structure and coating mechanisms of phenyl phthalimide and its derivatives during corrosion inhibition. The Monte Carlo simulation can simulate the real conditions of corrosion inhibition in the solution phase. PP-OCH 3> PP-Cl > PP-NO 2 The corrosion inhibition capacity of phthalimide derivatives is enhanced by phthalimide derivatives, according to PP-OCH 3 > PP-CH 3 > PP-Cl > PP-NO 2.
