ABSTRACT:
A method is described for treating high strength metals selected from zirconium, titanium and alloyed steels, against hydrogen embrittlement. The method involves the immersion of the metal in an electrolyte solution and subjecting it to an anodic potential having a value of up to 600 volts on the hydrogen scale. According to a preferred embodiment prior to the immersion, the metal is coated with a substance possessing a low hydrogen over-potential and high affinity towards hydrogen. The method removes continuously or periodically the hydrogen from the metal by anodic oxidation and minimizes the penetration of hydrogen into the core of the metal.
