摘要：
The influence of the SiCp proportion on the pitting corrosion of A3xx.x/SiC/xxp composites was Studied by means of potenciodinamic polarization and double cyclic polarization in saline environment at 25 degreesC. A360/SiC/xxp matrix does not contain copper, whereas the A380/SiC/xxp matrix contains 1,39-1,44w %Ni and 3,13-3,45wt %Cu. The kinetic study was carried out by gravimetric measurements. The nature of corrosion products was analysed by low angle XRD and Scanning Electron Microscopy (SEM). The corrosion is due to nucleation and growth of Al2O3.3H(2)O on the material surface. The corrosion increases with the reinforcement proportion, chloride concentration and copper content.
