Abstract
A systematic study of hydrogen permeation and its inhibition during a ferrous metal cleaning process was carried out. The amount of hydrogen that permeates a mild steel electrode of varyine thickness was investigated by the Devanathan-Stachurski method in commonly used cleaning solutions with or without corrosion inhibitors. The corrosion rates of the electrodes were determined by electrochemical methods at the same time. Specular reflectance FTIR spectroscopic measurements were used to obtain the structural information on the electrode/solution interface. The data were used to develop an effective method to prevent hydrogen damage in iron oxide cleaning processes.
