  • The possibility of copper corrosion protection in acidic media using a thiazole derivative = Možnost protikorozijske zaščite bakra v kislem mediju z uporabo derivatov tiazola
    Vaštag, Đenđi ...
    Assessing financial losses on an annual scale, it was determined that the world economy loses about 2.2 trillion US dollars as a result of the corrosion of materials. The most significant losses are ... caused by the corrosion of metals. Against corrosion, metals can be protected in several ways: by cathodic protection or anodic protection, by the use of inhibitors, or by using various protective coatings that can be metallic, non-metallic, organic or inorganic. In this paper, the possibility of the corrosion protection of copper was investigated in acidic media using inhibitors. The inhibitor properties of 5-(4'-dimetylamino- benzylidene)-2,4-dioxotetrahydro-1,3-thiazole, (DABDT) were tested on copper corrosion in an acidic sulphate-containing solution (0.1 mol dm[sup]{-3} Na2SO4, pH =3). Using potentiostatic polarization measurements, the inhibitor efficiency of DABDT as a function of concentration was determined and the mechanism of its adsorption on the copper surface was defined. It was found that the DABDT thiazole derivative acts as mixed inhibitor on copper corrosion in acidic media. In the investigation range, increasing the concentration results in a better inhibition efficiency of the DABDT.
