The Corrosin Properties of Nano-scale Twin Coatings of Nickel in Solution with Cl
A nickel coating with nano-scale twins (NT) was synthesized by using pulsed electrodeposition technique. And pulsed electrodeposition technique was optimized by orthogonal test, with corrosion resistance in solutions containing chloride ions as inspecting criterion. The results indicated that the as-deposited nickel coating with the best corrosion resistance was synthesized by the optimized plating parameters:positive average [...]
Study of SO42- and Cl- Ions on the Pitting Corrosion of Boiler Water-wall Tubes
As the increase of unit parameters, the quality of feed-water require more and more strict. If feed-water contains impurity ions exceeding allowed concentrations, boiler scale and corrosion accelerate, the waterside of water-wall tube corrodes, causing bursting of water-wall tube. Researching the influence of SO42- and Cl- ions on the pitting corrosion of water-wall tube, and [...]
Reliability Analysis of the Reinforced-concrete Bridges Considered Service Environment and Steel Corrosion Pattern
Corrosion of steel bars is the most important factor which causes failure of reinforced concrete bridges. The degradation caused by steel bar corrosion includes reduction of cross-sectional area, decrease of mechanical properties of steel and bonding between steel and concrete. These factors influence each other, and eventually lead to the structure failure. In this paper, [...]
