Abstract :
By properly proportioned SiC particles with different sizes and using squeeze infiltration process, SiCp/Al composites with highvolume fraction of SiC content (Vp = 60.0%, 61.2%, 63.5%, 67.4%, and 68.0%) were achieved for optical application. The flexuralstrength of the prepared SiCp/Al composites was higher than 483 MPa and the elastic modulus was increased from 174.2 to206.2 GPa. With an increase in SiC volume fraction, the flexural strength and Poisson’s ratio decreased with the increase inelastic modulus. After the anodic oxidation treatment, an oxidation film with porous structure was prepared on the surface ofthe composite and the oxidation film was uniformly distributed. The anodic oxide growth rate of composite decreased with SiCcontent increased and linearly increased with anodizing time.
