Abstract

Inside the concrete, stainless steel offers strength and corrosion resistance, giving the structure a long, maintenance-free service life. It is a steel alloy with a 10.5% chromium concentration. This study intends to determine the experimental parameters and evaluate the efficacy of the compounds as corrosion inhibitors for stainless steel in hydrochloric acid solution using the gravimetric technique and electrochemical measurements. Because of the way that chromium reacts with oxygen in the air to form a protective coating, stainless steel is extraordinarily resistant to corrosion and rust. In this investigation, corrosion inhibitors made from benzoic acid derivatives were applied to 316 SS in a 0.5 M hydrochloric acid solution. Scanning electron microscopy and energy dispersive spectroscopy (SEM/EDS) were used to study the surgical steel samples' outermost regions in either the absence or the presence of inhibitors. The samples were immersed in a hydrochloric acid solution. The fundamental properties of the studied inhibitors were also assessed using the dynamic molecular simulation (MD) method to assist the experimental research. The effects of different chemical levels and temperatures on inhibiting corrosion were investigated in order to determine the values of the activation and absorption features related to the corrosion process.

In light of the concentrations of the antagonists under research and the impact of ambient the temperature, the current research investigates the efficacy of inhibition. The best inhibitor concentration for C3 at 291 K was 1.0 102 M, and this resulted in the highest inhibition efficiency (88%).
