Metals interact with their surroundings to undergo corrosion, which is also defined as surface damage or metal decline in an aggressive setting. The objective of the current study was to assess the
ability of the green alga Chlorella sorokiniana MH923013 to prevent corrosion of stainless steel in saline medium. Atomic force microscopy (AFM) and Fourier transform infrared spectroscopy (FT-IR)
were used to analyse a dry mass of green algae. Electrochemical polarization technique was used to test the corrosion of stainless steel (S.S.) in saline solution (blank) and inhibitor (green algae)
solutions in various concentrations at temperatures ranging from 298 to 318 K. The kinetic and thermodynamic activation parameters (Ea, H, S, and G) for blank and inhibitor solutions were
