USE OF AN EMPIRICAL POTENTIAL SHIFT TECHNIQUE FOR PREDICTING DEZINCIFICATION RATES OF ALPHABETA-BRASSES IN CHLORIDE MEDIA

The experimental results have clarified the conditions necessary for producing either layer or plug type dezincification in alpha beta -brasses and have also provided additional information relevant to the mechanism of dezincification. The technique has also confirmed that provided the potential requirements were met, accelerated dezincification could take place in domestic tap waters normally considered nonaggressive. It would, therefore, appear possible to apply a unifying theory as to the cause of dezincification, irrespective of the conditions of exposure.
