... of total sulfide to total iron was 5.24. Calculated SI values of FeS using ScaleSoftPitzer^TM 2019 software developed by Rice University were 2.2 at pH 6.7 and 0.8 at pH 5.2. The SI value of Barite was 2.0 at both pHs. FeS scale inhibition and dissolution Abstract Sulfide scales...

...In the geological field, since carbonates are very commonly found as minerals, extensive studies have been made to understand the mechanism of dissolution 5 - 9 . Dissolution kinetics of iron carbonate was studied for a range of temperatures and pressures ^{10 - 16} . The effects...

...In the present work we have investigated the growth and dissolution of calcium carbonate in the presence of various additives, involving groups which may be ionized in aqueous solutions and have therefore the potential of interaction with solid surfaces. Both in crystal growth and dissolution...

...Abstract Combination of a constant composition (CC) crystallization approach together with atomic force microscopy (AFM) has enabled the elucidation of the mechanisms of the scale (crystals) formation and dissolution at the molecular level. The new model reveals that the surfaces may be unable...

... have studied on the corrosion behavior of alloy 625 and its constituent metals (Ni, Cr and Mo) in 0.05mol/kg HCl + 0.48mol/kg O₂ at 350°C and 24MPa. They found that pure Ni suffers from severe general corrosion, and pure Cr and Mo undergo transpassive dissolution 9 . Aki et...

... specimens measured after the removal of oxide films provides the net weight loss of the metal, ΔW_Fe,net, which corresponds to the total weight of the metal consumed by corrosion including oxidation and dissolution. Figure 3 shows the changes in ΔW_Fe,net...

...(I) using the ring current for Cu(I) oxidation measured at +0.4 V. At a ring potential of -0.4 V copper is plated onto the ring electrode and, at high disc dissolution rates, the collection efficiency was observed to increase with time, presumably as a consequence of changes in the hydrodynamic...

... initiation and propagation fracture surfaces. The initiation surfaces show evidence of dissolution, and propagation surfaces exhibit characteristics of microcleavage. Different fundamental mechanisms probably operate during these two stages. In the past, the bulk of the research effort has been devoted...

...Silicon is another important minor element that influences dissolution and passivation in Fe-Ni-Cr stainless alloys. Bulk additions (up to ~8 at%) can accelerate dissolution at transpassive potentials, but also improve passivation (and resistance to localized corrosion) at lower potentials. ²...

..., but these factors were not investigated in this report. The dissolving ability is not analogous to acid dissolution of CaCO₃ and therefore this chemical dissolver has more specialized applications. Several case histories of successful applications of this chemical dissolver are presented. Related...

Analytical electron microscopy measurements reveal silicon enrichment and chromium depletion at internal interfaces in irradiated specimens. Silicon enhances dissolution at transpassive potentials, whereas chromium depletion...
