| 摘要： | The effects of cathodic protection on the embrittlement of high strength steel embedded in concrete were studied. The results show that cathodic protection will generate hydrogen on the steel if the potential is more negative than the thermodynamic hydrogen evolution potential. The atomic hydrogen generated will enter the steel and cause a loss in ductility which will adversely affect the steel's performance if a notch is present. Studies are continuing on full-scale beams to study the effect and effective cathodic protection criteria. |
