Zn‐TiO2 composite coatings were electrodeposited on mild steel using an electrolyte containing dispersed nanosized TiO2. The corrosion resistance of the coating was studied in (3.5 wt.%) NaCl solution by electrochemical and weight loss measurements. The study revealed higher resistance of composite coating to corrosion. The composite coatings were porous free and the service life of coatings was examined by salt spray test. The surface morphology was investigated by recording the scanning electron microscopy (SEM) images of coating before and after corrosion. SEM studies inferred the reduction in crystalline size of composite coating and it showed the improved corrosion resistance property. The anti‐corrosion mechanism of the composite coating was also discussed.
