Abstract

Friction stir processing (FSP) is a new solid state technique for microstructural modification in metallic materials. This has been used to develop a new method for surface composite fabrication. Examples of various SiC reinforced aluminum matrix surface composite are reviewed in this paper. This relatively fast solid state process avoids phase stability issues encountered with most surface modification technique involving melting of base material. the transition interface from unreinforced to reinforced region shows excellent bonding. a critical issue at this stage is the non-uniformity of friction stir surface composite (FSSC) layer. Tool modifications are needed to obtain uniform FSSC layer. the FSSC layer exhibits significant improvement in hardness.
