The corrosion behaviour of brass has been studied from an aspect of dezincification mechanism of cold-deformed CuZn-42 brass were tested in acid sulphate solution at pH-value 2 with additional chloride ions and corrosion inhibitors with potentiostatic polarization method. Thiourea (TU), benzotriazole (BTA), ethylene diamine tetraacetic acid (EDTA), hydrazine sulphate (HS) and 2-butin-1,4 diole (DS-3) have been used as effective acid corrosion inhibitors. Increase of a concentration of the Cl– ions, exept for value of 5ź10(-2) moldm(-3), resulted in a significant increase of value for corrosion current densities. In solution without inhibitors, process of dezincification and anode dissolution of CuZn-42 brass was developed in the whole range of tested potentials, and pointed out the unstability of formed on their surface. The results of studies show that only thiourea, in concentration of 10(-2) %, inhibit the corrosion of brass in chloride solutions. Inhibitor benzotriazole in concentration of 10(-1) % inhibit the corrosion of brass with inhibition efficiency more then 94 %. The film improved significantly the protecting ability of brass surface to corrosion in chloride solutions. When the films were modified with benzotriazole the quality and corrosion protection of films improved rapidly.

Badano korozję mosiądzu CuZn-42 w roztworze kwasu siarkowego (pH2) z dodatkiem jonów chloru i inhibitorów metodą polaryzacji potencjostatycznej. Stwierdzono, że wzrost koncentracji jonów Cl– ponad wartość 5ź10(-2) moldm(-3), powoduje wyraźny wzrost korozji i gęstości prądu. Wykazano, że tylko dodatek tiomocznika (stężenie w roztworze 10(–2) %) hamuje korozję mosiądzu w roztworze chlorkowym.
