Corrosion Behavior of Foamed SiC /Cu Co-continuous Composite in Salt Spray
|
Abstract:
The corrosion behavior of foamed SiC/Cu co-continuous composite and the corresponding matrix material Cu was examined by 5.0% NaCl salt spray and then characterized by means of weight-loss,SEM and XRD.The results show that the outer corrosion products of the two materials are the same,aeruginosa Cu2Cl(OH)3 and the inner layer is Cu2O,a protective layer.The foamed composite is corroded faster than pure copper in NaCl aqueous solution.It could be mainly attributed to the special structure of the foamed SiC/Cu...
