Abstract :

Inhibitory effect of 1 – Phenyl –3 – Methylpyrazol –5– One (HPMP) on the mechanical properties of copper in acid environments was studied using weight loss method. Results obtained showed that HPMP inhibited the corrosion of copper in Hydrochloric and Nitric acids, but didn’t in Perchloric acid environment. Calculated values of rate constants and half –life confirmed the inhibition of the metals by HPMP. HPMP is therefore a good and effective inhibitor for copper, as it caused a remarkable decrease in the hardness and tensile strength of the coated coupons, rendering them more ductile compared to the uncoated coupons.
