<![CDATA[Corrosion is an electrochemical reaction that causes damage to metals due to interaction with the environment, where the metal undergoes oxidation and oxidizing agents such as oxygen undergo reduction. 316l tainless steel is a metallic material characterized by high Surface deterioration resistance, but can still experience degradation in strong acidic environments such as hydrochloric acid (HCl). Efforts to slow the corrosion rate can be done by adding chemical inhibitors. This study seeks to evaluate the effect of adding two types of Compound inhibitors on corrosion resistance and morphological changes in 316l stainless steel immersed in HCl solution. The inhibitors used in this study were Sodium Benzoate (NaC₇H₅O) and Sodium Silicate (Na₂SiO₃) each with a concentration of 8 grams. Immersion was carried out in three time variations, with immersion durations consisting of 6, 12, and 18 days.. The research methods used include observing the corrosion rate based on the sample mass before and after immersion, as well as documenting changes in surface morphology using a cellphone camera and SEM (Scanning Electron Microscope). The anticipated results of this research are to assess the performance of each inhibitor in reducing corrosion and to examine the resulting changes in the surface morphology of Stainless Steel 316L]]>
