CORROSION INHIBITION OF COPPER IN 0.5 M HYDROCHLORIC ACID BY 1,3,4-THIADIAZOLE-2,5-DITHIOL
The inhibition of copper corrosion by 1,3,4-thiadiazole-2,5-dithiol (bismuthiol), under 0.5 M HCl at 25 C, was studied by means of the potentiodynamic polarization technique. It was found that bismuthiol was chemically adsorbed on the copper surface, and follows a Langmuir isotherm. The inhibition m...
