The study of structural and electrical properties OF ZnO nanostructures layer coated on mild steel surface / Muzammil Mat Akhir

Zinc coated mild steel is usually applied to protect the surface from corrosion. In this study, Zinc Oxide nanostructure is applied on the surface of mild steel. The Zinc Oxide nanostructure was synthesized using sol-gel method. After the solution was prepared, it is coated on mild steel surface using spin coater at 2000 rpm and anneal at different temperature to see the effect of Zinc Oxide growth. After the sample has been coated it will characterize using FESEM, AFM, XRD and Linear Polarization. For surface morphology the figure showed different structural size and pattern at higher anneal temperature. The AFM used to investigate the surface topography and measure the average roughness of coated sample. For sample at 500°C the surface roughness is higher about 41.88 run. XRD used to determine the composition of ZnO on mild steel surface. Lastly, the linear polarization resistance used to see the performance of coated sample. The lower corrosion rate obtained for sample that anneal at 300°C.
