Effect of Green Inhibitors on the Corrosion Rate of Mild Steel and Stainless Steel 304

Corrosion is an inevitable process that affects metals in everyday life, requiring constant efforts to manage due to its technical, economic, and aesthetic significance. It refers to the degradation of metal surfaces caused by reactions with environmental elements. The damage caused by corrosion can be severe, leading to structural failure of metal components, increased repair and replacement costs, product losses, and even safety hazards, as well as environmental pollution. One effective method of mitigating corrosion is the use of inhibitors. These are chemical agents added in small amounts to reduce the corrosion rate. With growing awareness of environmental and health concerns, the focus has shifted towards developing eco-friendly, non-toxic corrosion inhibitors derived from natural sources. In this study, the inhibition of corrosion on mild steel and stainless steel in corrosive environments such as hydrochloric acid was explored using green inhibitors. These inhibitors were extracted from natural sources like Cinnamomum verum (cinnamon) and Aloe barbadensis (aloe vera) in the form of oils and gel. The study was conducted at room temperature using the weight loss measurement technique to assess the effectiveness of these inhibitors.
