THE INFLUENCE OF METAL IMPURITIES
IN CHLORIDE ACID ZINC COATING
The paper present the some defects caused by impurities, acid zinc
coating occurred in practice, defects can be fixed depending on the nature of
the case, reversible reactions, or the time of referral. Conclusions drawn from
the study of the influence of metal impurities. Like all plating baths, acidic
galvanizing bath is very sensitive to metal pollution and aggressive foreign
electrolyte greatly increases the risk of such pollution. Particular attention
should be given to measures to avoid the intake of foreign metal galvanizing
bath and their immediate disposal, where their presence is found.
