The performance of a fatty acid amide inhibitor synthesized from the coffee bagasse oil has been evaluated by electrochemical techniques such as potentiodynamic polarization curves, open circuit potential measurements, linear polarization resistance, and electrochemical impedance spectroscopy. Inhibitor concentrations included 0, 5, 10, 25, 50, and 100 ppm. Inhibitor efficiency was evaluated on an X70 steel in a CO₂-saturated brine at 60°C. All the different techniques have indicated a decrease in the cathodic current density and inhibitor efficiency values as high as 96%. The inhibitor was chemically adsorbed on to the steel according to the analysis of the inhibitor adsorption process.

由咖啡渣糖油合成的脂肪酸酰胺抑制剂的性能已通过电化学技术进行了评估，如电位动力学极化曲线，开路电势测量，线性极化电阻和电化学阻抗谱。抑制剂浓度包括0、5、10、25、50和100 ppm。抑制剂效率上的X70钢评价在CO ₂在60 -饱和盐水℃。所有不同的技术都表明，阴极电流密度的降低和抑制剂效率值高达96％。根据抑制剂吸附过程的分析，将抑制剂化学吸附到钢上。
