Abstract
Concerning hydrogen embrittlement of corroded bridge wires, the effects of diffusible hydrogen concentration to corrosion progress and the effect of introduced stresses to high strength galvanized wires were investigated. Hydrogen concentration directly relates with hydrogen embrittlement. The three corrosion level specimens were produced and then the concentration of the diffusible hydrogen was measured by the gas chromatography with scanning temperature. The concentrations of the corrosion level 1 to 3 specimens and those with tension or non-tension were all between 0.1 to 0.2 ppm. This value is well below the critical diffusible hydrogen concentration of 0.6ppm to cause embrittlement.
