Correlation of Laboratory Results with Observations on Long-Term Corrosion of Iron and Copper Alloys

Abstract

The data base for compounds produced during long-term corrosion of iron and copper objects is reviewed. Compounds are identified that occur in long-term but not in short-term corrosion. Where possible, the formation of these compounds is explained or at least rationalized. An effort is made to discriminate those compounds whose formation depends on microbiological action from those forming abiotically.

Volume II: near-field and altered-zone environment report

“…That diffusion-controlled phenomem should be expected overtime periods of at least 2,000 years is apparent from investigations of corrosion phenomena in ancient bronzes . Development of some phases appears to be mediated by the activity of microorganisms (McNeil et al, 1990).…”

Near-field/altered-zone models report

“…Near-Field/Altered-Zone Models Report UCRL-ID-129179 (McNeil et al, 1990). In addition, some information on the long-term corrosion of materials has being assembled from the New Zealand analog site .…”

Engineered materials characterization report, volume 3 - corrosion data and modeling update for viability assessments

“…That diffusion-controlled phenomena should 5-10 be expected over time periods of at least 2,000 years is apparent from investigations of corrosion phenomena in ancient bronzes (Scott, 1985). Development of some phases appears to be mediated by the activity of microorganisms (McNeil et al, 1990). In addition, some information on the long-term corrosion of materials has been assembled from the New Zealand analog site (Bruton et al, 1995, Meike, 1996.…”
