Inhibitive effect of black pepper extract on the sulphuric acid corrosion of mild steel / Nabilah Nooh

The corrosion inhibitive effect of the extract of black pepper {Piper nigrum plant) on mild steel (MS) in IMH2SO4 media was evaluated by electrochemical studies (Tafel polarization), Fourier transform infrared (FTIR) and scanning electron microscope (SEM) studies.Generally, corrosion rate informatio...
