| Abstract: |
| Using brazing technique and Zn A125 as brazing alloy,the Al 9Si alloy cohered with a thin layer of composite material Al 9wt%Si 15vol%SiCp was successfully fabricated under protection atmosphere of N2 by strictly controlling the technological process.The fabricating of Al 9Si alloy part with a surface layer of composite material provided a new way of surface treatment for Al alloys.The properties of parts with composite structure were also investigated in this paper. |
