Abstract

Corrosion is a material whose process is slow. Various factors can influence corrosion, including the environment of the metal mixture and others. Aluminum is easily formed, can be forged into sheets, drawn into wires, and extruded into rods with various cross-sectional shapes. Inhibitors are generally chemical substances. The use of three different types of solutions has a significant effect on the corrosion rate on the surface of the 1100-0 aluminum plate. HCl solution shows the highest level of corrosivity because it is a strong acid that can dissolve the protective oxide layer of aluminum, thereby accelerating the electrochemical reaction and significantly increasing the corrosion rate. The use of inhibitors in the form of epoxy paint is necessary to protect the surface of 1100-0 aluminum because this material is susceptible to corrosion when directly exposed to acidic, oxidative, or basic solutions. Epoxy paint functions as an effective barrier layer to prevent direct contact between the aluminum surface and the corrosive environment.
