Abstract:

The objective of this research is to define the conditions under which pollutants, in particular those produced by bacteria such as the sulfide end product of the SRB, affect the amount of hydrogen absorbed by ironsteel during open circuit corrosion and under cathodic polarization conditions. At the same time we will be investigating protective measures including the development of improved inhibitors that will work under occluded conditions as exist during microbiological corrosion and localized corrosion in general.
