摘要

The effect of 1-Phenyl-3-Methyl Pyrazol-5-one (HPMP) on the electrical properties of high carbon steel in Hydrochloric acid (HCI), Trioxonitrate (v) acid (HNO3) and Perchloric acid (HCIO4) was studied by weight loss method. The acidic medium caused a complete degradation of the electrical properties of the coated and uncoated high carbon steel. However, the attack was more on the uncoated coupons, which showed that HPHP is an effective corrosion inhibitor. HNO3 had the most severe effect on the metal. The coupons coated with HPMP generally had higher values of resistance (0.0155 Ω) and conductivity (6.20 mho/m) in HCI environment than the uncoated coupons (0.0043 Ω) and (1.72 mho/m). Similar results were obtained for HNO3 and HCIO4 environments. These values are lower than the values obtained for as-received coupons: -0.0466 and 8.64 mho/m respectively.
