A GEOCHEMICAL MODEL FOR PREDICTING CORROSION- SCALE DISSOLUTION AND PHASE TRANSFORMATIONS IN DRINKING WATER DISTRIBUTION SYSTEMS
… for varying water chemistry conditions and corrosion scale compositions. The equilibrium model is developed in PhreeqC.v.2.16.03 with reactions and thermodynamic constants validated by comparing simulation results with laboratory batch dissolution experiments. The experiments were conducted …

In-operando techniques for early-stage corrosion
… approaches are investigated to study corrosion at the solid/liquid interface, at a higher spatial and temporal resolution than previously possible. Corrosion remains a pernicious concern for metallic structure stability. This is evident in the common case steel in contact with water, …

Iron Release From Corrosion Scales in Old Iron /Steel Drinking Water Distribution Pipes
… the issues of the formation and growth of iron corrosion scales, and their reactions that lead to colored water problems. According to the model, iron release from corrosion scales can be controlled, in general, by either (a) promoting a denser scale microstructure, or (b) inhibiting dissolution …

Effect of Vanadium on High Temperature Corrosion of Alloy Steel
… processes in industries. However, their corrosion performance needs to be further evaluated in order to consider them a vital alternative for corrosion application. This research was focused on the performance of this material at high temperature corrosion. Three materials were selected …

The Effect of Water Chemistry on the Properties of Iron Particles and Aqueous Iron Suspensions Derived From the Oxidation of iron(II)
… in understanding the properties of iron corrosion scale and deposits, iron release mechanisms, the stability and mobility of iron particles in water, and the color and turbidity of aqueous iron suspensions. Their properties are also important in source water iron removal effectiveness, …

Water Quality Factors Influencing Iron and Lead Corrosion in Drinking Water
Corrosion is one of the most complicated and costly problems facing drinking water utilities. Corrosion of iron pipes can lead to economic losses and customer complaints, while lead corrosion poses a serious health risk. This work first synthesizes nearly 100 years of iron corrosion research to …

Dezincification and Brass Lead Leaching in Premise Plumbing Systems: Effects of Alloy, Physical Conditions and Water Chemistry
… it is important to examine dezincification corrosion in more detail. An in-depth literature review revealed that conventional wisdom about dezincification was no longer adequate in explaining failures observed in modern water systems. Little research has been conducted since the landmark …

Influence of Water Chemistry Parameters on the Dissolution Rate of the Lead (II) Carbonate Hydrocerussite
… dissolved lead dissolution curves at short time scales (hr.). All equilibrium dissolved lead concentrations were achieved in 40 minutes or less, and matched trends from previous studies; pH 7.5 and pH 10 corresponding to the highest and pH 9 presenting the lowest equilibrium lead concentrations. …

Change Of Metal Oxidation State At High Temperature, Impact Of Temperature And Reactive Gases
… mg/kg forming eutectics that accelerate corrosion on the metal alloys present. Similarly in catalysis, there are reactive intermediates that remain attached to the catalytic metal surfaces resulting in volatile metal complexes forming leading to losses via elevated vapor pressures at …
