Anp. Tendulkar et Tp. Radhakrishnan, A GALVANOSTATIC STUDY OF THE ROLE OF ARSENIC ON THE ENTRY OF HYDROGENINTO MILD-STEEL, Corrosion science, 36(7), 1994, pp. 1247-1256
The role of arsenic, present in traces as arsenite in 0.1 N H2SO4, in
enhancing the entry of hydrogen into mild steel during cathodic chargi
ng has been studied. The electropermeation method with galvanostatic m
ode of charging the steel has been adopted to assess the extent of per
meation of hydrogen, during both transient and long duration charging.
The permeation technique has been coupled with a radiotracer method t
o help identify the nature of the arsenic species which promotes the u
ptake of hydrogen.
