Abstract
In this work, a comprehensive study for using (2E)-N,6,6-triméthyl-N-(naphtalén-1-ylméthyl) hept-2-én-4-yn-1-amine as a corrosion inhibitor for copper in a Molar Sulfuric Acid Solution was performed. For this purpose, both types of electrochemical have been applied. The obtained experimental results showed that the investigated compound is a promising corrosion inhibitor for copper in acidic(0.5M/H2SO4) environments. The inhibition efficiency increases with increasing inhibitor concentration. Adding a low inhibitor molecule(Terbinafine) concentration of about 5 × 10−3 M at 303K resulted in an inhibition efficiency of up to 95.20%. Terbinafine C21H25N appears to have an anodic character, according to the polarization curves. Terbinafine protects the copper metal through adsorption on its surface by obstructing its active sites, according to Scanning electron microscopy SEM surface examination.
