Abstract

1432313 Cathodic protection using zincindium anodes METALLURGIE HOBOKENOVERPELT 12 March 1974 [19 March 1973] 11021/74 Headings C7A and C7E Tanks containing alternately crude oil and water are cathodically protected using zinc alloy anodes of composition 0.005 to 0.02% Indium balance zinc of impurity content:- maximum Fe 25 ppm, maximum Cu 5 ppm, maximum Pb 30 ppm, maximum Cd 30 ppm. The alloy may be prepared from a melt of zinc and indium at 500 to 550‹C which is homogenized for 15 minutes and cast at 450-550‹C.
