    It has been confirmed that corrosion inhibition mechanisms of various inhibitors are closely related to the hard and soft acids and bases principle (HSAB principle). The inhibition mechanisms of cationic and anionic precipitation inhibitors in aerated neutral solutions are discussed based on the HSAB principle in this review. Cooperative inhibition of cationic and anionic inhibitors is also described. The effect of ligand field on the corrosion inhibition is discussed on the basis of the principle.

    The effects of the annealing temperature on the electrochemical properties, anodic dissolution, and pitting corrosion resistance of MnS inclusions in 18mass%Cr ferritic stainless steel are investigated by scanning electron microscopy, macroscale polarization, and microscale polarization. The MnS inclusions in the specimens annealed at higher temperatures have higher Cr concentrations and lower Mn concentrations. The onset potential of the inclusion dissolution and the pitting corrosion resistance of the MnS inclusions increase with an increasing annealing temperature.

    Synergistic inhibition effects of sodium octylthiopropion-ate NaC8H17S(CH22CO2(NaOTP) and various metallic cations were investigated on iron corrosion in aerated 0.5 M Na2SO4 by polarization measurement and X-ray photoelectron spectroscopy (XPS). Lower inhibition efficiencies than the efficiency of 3×10-4 M NaOTP alone were obtained by the addition of 1×10-4 M cations, Al3+, Ga3+, Y3+, La3+ and Ce3+ to the solution where precipitates formed. Although clear solutions appeared by reducing the concentration of the cations, no synergistic inhibition effect of NaOTP and the cations on iron corrosion was observed. Addition of 1×10-4 M Zn2+ to the 3× 10-4 NaOTP solution, in which no precipitate formed, resulted in synergistic inhibition. XPS showed on the iron surface covered with a chelate precipitate composed of OTP and Zn2+.
