Inhibition of Localized Corrosion.
Abstract
Initial testing in this program confirmed that N-lauroylsarcosine (NLS) provided protection against pitting in chemically simple systems which was similar to that which we had observed in more complex SO2 scrubber solutions. Further experimentation resulted in developing a galvanodynamic method for determining the electrochemical pitting parameters in inhibited solutions which has proved quite useful and reliable. The effects of varying a large number of environmental variables on these pitting parameters were investigated using Type 304L stainless steel in inhibited and uninhibited solution. Theses variables included the chloride concentration, pH (in both buffered and unbuffered solution), inhibitor concentration, solution agitation, and various means of exposing the sample to the inhibitor. Papers are included as appendices: Inhibition of localized corrosion as determined by galvanodynamic method; Inhibition of pitting of type 304L stainless steel by NLS and by surface active compounds; Spontaneous formation of multimolecular layers by pitting inhibitors. Keywords: Corrosion inhibition; Linear current scan.
