Inhibition of steel corrosion by synergized leave extracts of Sida acuta and Jatropha curcas as additives substitute to synthetic compounds in Alkyd based Primer coats was investigated in 1.0 M HCl using the gasometric technique at 30°C and 50°C. Results obtained showed that the extract alternative effectively inhibited corrosion of degalvanised steel more than the synthetic chemical. This was confirmed by optimum inhibition efficiency of 93% to 90% corrosion rate 0.202 cm3/hr to 0.337 cm3/hr of the extract to the synthetic compound. Activation energy and Energy of adsorption decrease with time. Fourier transform infra red analysis confirmed the presence of C=O of ester by the presence of C-O functional band at 1094 cm-1. Surface morphology of the steel with the synergized were studied with Scanning electron microscope (SEM) and Electron dispersive X-ray spectroscopy (EDX) which revealed the protection of the internal grains of the metal from dissolution into corrodent provided by the adsorbed film the extract.
