W. Baptista et G. Pimenta, CATHODIC PROTECTION AGAINST CREVICE CORROSION OF HIGH-ALLOY STEEL IN SEAWATER, Materials performance, 34(10), 1995, pp. 29-32
Localized corrosion of high-alloy steel in seawater, mainly under crev
ices, limits the alloys' use in such environments. An in-situ test pro
gram was conducted to study this corrosive process and possible protec
tive measures. Attention focused on the resistance of several types of
high-alloy steels under corrosive conditions and on the response of t
ype 316 stainless steel to cathodic protection (CP) by carbon steel an
d zinc anodes. It was found that CP could effectively mitigate crevice
corrosion in these subsea conditions.
