Corrosion behaviour on AA2014/15vol. %A1₂0₃P and AA2009/20vol. %SiCw composite after ageing treatment

The purpose of this study is to compare the corrosion behaviour between AA2014/15vol. %A1₂0₃P and AA2009/20vol. %SiCw composites after ageing treatment. The former composite was cast composite supplied by Duralcan USA. The later composite was a powder metallurgy composites supplied by Advanced Compo...
