This article proposes the effects of temperature on corrosion inhibition of hydrochloric acid (HCl) solution for low carbon steel with a weight loss process. The corrosion process was tested at temperatures of 25, 35, 45, 55, and 65oC, the inhibitor bulrush was used with concentrations of 0, 0.2, and 0.5 g/L, and hydrochloric acid was used as a solution. The experiment suggests that increasing inhibitor concentration leads to a decrease in corrosion rate in HCl solution due to diffusivity and oxygen solubility. Also, corrosion rate increases as temperature increment and bulrush inhibition efficiency increase with increasing inhibitor concentration up to a maximum of 97.73% at 25 oC and 0.5 g/L concentration. These results revealed that bulrush inhibitor is the best result due to creating a thicker and stronger adjacent layer on the metal surface to prevent dissolved oxygen to reach the metal surface. In the same matter, limited current density increased with increasing temperature and decrease with increasing inhibitor concentration.
