Summary, etc. <p><strong>Abstract: </strong></p><p>This paper investigates electrochemical behaviour of Cu24Zn5Al alloy in a sodium tetraborate solution in the presence of 1-phenyl-5-mercaptotetrazole (PMT).Investigations were made of the influence of PMT concentration, chloride ion concentration and the immersion time on the alloy behaviour by employing the technique of mass loss determination and by anodic polarization. Corrosion potential was also measured and the surfaces of the alloy were recorded using optical microscopy. According to the obtained results 1-phenyl-5-mercaptotertazole shows good inhibiting properties for the investigated alloy. The inhibition mechanism is based on the formation of a Cu-PMT polymer film. Using the Langmuir isotherm the adsorption energy was found to be in the interval from -33.8 to -37.7 kJ/mol.</p>
