Corrosion is a serious threat to the long-term function and integrity of steel. Structural steel will corrode if left exposed or incorrectly shielded from the natural environment. Corrosion might take the form of general uniform thickness loss or localized pitting, depending on the climate. The goal of this study is to use the weight loss method to determine the mode of action of wild yam (dioscorea villosa) extract on mild steel in a 1 M H2SO4 solution. The synergistic corrosion inhibition of mild steel in 1M H2SO4 media utilizing extract of wild yam (dioscorea villosa) was examined using the weight loss method. The inhibitory efficacy of the extracts improved as the concentration of the extract increased but reduced as the temperature increased. Inhibition was found to be beneficial in a range of situations: 16.67-33.33% at 30oC, 28.50-57.14% at 40oC, 11.11-44.44% at 50oC, 7.41-18.52% at 60oC and 7.69-15.31% at 70oC. A wild yam (dioscorea villosa) extract reduced mild steel corrosion, according to the findings. The extract of wild yam (dioscorea villosa) is a good synergistic green corrosion inhibitor since it reduces the rate of corrosion significantly.
