Pitting corrosion is an insidious form of localized corrosion a ecting characteristics of various engineering metallic alloys. Currently very limited literature exists with regard to systematic characterization of pitted surfaces or the efficient use of numerical methods to assess its effect, i.e. fatigue life reduction caused by the state of a corroded specimen and particularly through the stu...
Background: This study investigated the prevention of stack corrosion under wet flue gas desulfurization conditions in a coal-fired power plant. The performance analysis and comparative studies of six materials for the prevention of stack corrosion were investigated. Results: The ion chromatography analysis showed the acid condensation contained fluoride, chloride, nitrate, sulphate, and sulphi...
An innovative sensor containing A36 carbon steel was explored for corrosion monitoring. After being soaked in an aerated 0.2 M NaCl solution, the sensor’s normalized electrical resistance (R/R0) decreased continuously with the extent of corrosion from 1 to 0.64. Meanwhile, the sensor’s normalized capacitance (C/C0) increased continuously from 1.0 to 1.42. The sensors can be attached to a struct...
The iNEMI technical subcommittee on creep corrosion is developing a flowers-of-sulfur (FOS) based qualification test for creep corrosion on printed-circuit boards (PCBs). The test setup consists of a 300-mm cube chamber with two means of mounting the test specimens and flowing air over them to expose them to constant, predefined humidity and temperature conditions and sulfur and other contamina...
