摘要:The impact of the inhibitor addition in the form of BWP extract in the corrosive environment was reviewed on the E-pH diagram of 304SS. This steel has a main constituent element such as Fe (iron), Cr (chromium) and Ni. Based on the E-pH diagram of Cr and Ni, it is known that the steel is corrosion resistant, as it will form a passivation layer as a protection from corrosion. E-pH diagram is generally constructed with complex thermodynamic calculations or using a certain software. In this research, the construction of E-pH diagram based on experimental results was conducted. The environment control by using an inhibitor is the one by modifying the environment. This study is a continuation of early research on the characteristics of the extract BWP as a corrosion inhibitor. The addition of inhibitor will change the E-pH diagram of 304SS. The research was conducted by potentiodynamic testing. Scan rate used was amounted to 0.001 V / s. The result indicates the presence of E-pH diagram changes with the addition of BWP inhibitor. This study also characterized the thin film surface with atomic force microscopy (AFM).
