Present progress on studies of reinforcement carbon,silicon carbide and alumina surface coatings in aluminium metal matrix composites

The interface between the matrix and reinforcement plays a crucial role in determining the properties of metal matrix composites (MMC).Surface treatments and coating of the reinforcement are some of the important techniques by which the interfacial properties can be improved . Reinforcement coatings are classified as metallic,ceramic,bilayer and multilayer coatings. Fabrication methods often include electroless plating ,chemical vapor deposition,and sol gel technique, etc. Coatings on three important reinforcements, such as carbon, silicon carbide (SiC) and alumina (Al 2O 3) and their effects on the interface and properties of aluminium alloy matrix composites are reviewed.
