The effect of surface oxidized modification on the mechanical properties of SiC _3D /Al

In this study, the effect of surface oxidized modification on the mechanical properties of silicon carbide 3D/aluminum composites (SiC _3D /Al) is explained. The basis of this study may be outlined as follows: the shear force of extrusion testing proves the effect of SiO ₂ layer thickness from the perspective of interface failure mechanism; and the critical pore radius explains the effect of SiO ₂ layer distribution from the perspective of a biconnected structure. The compression and flexural tests prove that compressive strength is mainly affected by the average SiO ₂ layer thickness. Bending strength is affected by the critical pore radius, which is the primary contributor to SiO ₂ layer thickness of the special structural space and stress concentration. Thus, the structural characteristics of SiC _3D /Al affect the SiO ₂ growth mechanism, as indicated by the aforementioned results.
