Abstract: | The inhibitive effect of carica papaya leaves extracts on the corrosion of mild steel in seawater will be investigated. The study been carried out using the mild steel SS400 and carica papaya leaves extract as a corrosion inhibitor. The constituent of carica papaya leaves extracts showed that it has potential as inhibitors of SS400 mild steel corrosion in seawater and marine environment. The laboratory immersion test technique been used to study either carica papaya extracts is a good corrosion inhibitor in the weight loss method and electrochemical experiments. The components of carica papaya leaves extract were studied through fourier transform infrared spectroscopy (FTIR). Type of natural inhibitor, and inhibition efficiency were studied through Polarization Test and Impedance Test by electrochemical impedance spectroscopy (EIS). Based on the test that have been done, several objectives been achieve, that is the effect of carica papaya leaves extract for the inhibition of mild steel in seawater, the corrosion inhibition efficiency of the carica papaya leaves extract by using electrochemical impedance spectroscopy, the corrosion inhibition of carica papaya leaves extract inhibitor with respect to immersion period and get to identify the functional group in carica papaya leaves that help it to be good corrosion inhibitor. |
