Al-NANOSTRUCTURED FILM COATING ON MILD STEEL SURFACE FOR CORROSION PROTECTION

Abstract

Nanostructured coating is a great and important for surface coating industries, especially in oil and gas, and automotive. This type of coating is expected to improve three times longer than a normal coating in corrosion protection. The nanostructured coating will fill up the uneven surface substrate at the size of nanometer compared to the normal coating which only cover the substrate surface. The void between the substrate and coating material initiate corrosion activities. In this work Aluminum nanostructures coating was deposited on mild steel surface by an electron beam thermal evaporator. The parameters used to optimize the coating is power and time exposure. The formation of nanostructures coating was measured by AFM, FESEM and EDX. The deposition of Al-nanostructured on mild steel substrate was carried out by applying deposition time of 2 min and 5 min with various current deposition such as 60A and 70A. The results show the formation of nanostructures film coated on mild steel in certain parameter.
