摘要：

A number of chromated Zn-Fe (0.3% Fe) samples were corrosion tested in a 3% NaCl solution of pH 5.000 by means of simultaneous corrosion measurements by titration and electrochemical measurements. In one experiment lasting 95 h the corrosion rate was constant, although the dissolution valence fell from nearly two to one, while the corrosion potential increased by some 120 mV. A reaction scheme consistent with these observations is proposed.
