高纯Fe中氢损伤规律的研究

本文采用正电子湮没技术研究了高纯Fe中的氢损伤规律,实验结果表明,在0.5mol/L H_2SO_4溶液中不加毒化剂电解充氢时,产生氢损伤的临界电流密度为20 mA/cm~2;而在0.5mol/L H_2SO_4溶液中加少量As_2O_3作为毒化剂电解充氢时,即使很小的电流密度也会产生氢损伤,配合慢...

Hydrogen damage in iron or 99.99% purity has been investigated by Doppler broadening measurement.Experimental results show that when the iron is charged with hydrogen in 0.5mol/L H_2SO_4 solution,the critical current density to cause hydrogen damage is 20mA/cm~2.While a little As_2O_3,saying 250mg/L...
