摘要：

The present study signifies the role of nickel oxide along with cerium oxide on barrier protection of aluminium as a metal matrix composite for marine applications. The incorporation of cerium oxide and nickel oxide in pure aluminium had improved the corrosion resistance and microstructure of the composite. A relatively anodic and stable OCP was exhibited throughout the period during long-term evaluation. Both nickel oxide and cerium oxide acted synergistically to reduce corrosion in aluminium. The mechanisms of barrier protection of the composites are discussed predominantly based on extensive impedance analysis. The results signify the scope of potential use of the composite in marine environment. (C) 2009 Elsevier B.V. All rights reserved.
