Pressureless Infiltraion techmique featuered by its facility and economy is employed to fabricate SiCp/Al
alloy composites with self-prepared equiprment. Molten aluminum alloy is hard to wet and infihrate into SiCp
reinforcement, Processing conditions for bettering the wettability and spontaneous infilration of liguid aluminum alloy
into SiCp are investigated. Factors influence the interface reactions are also discussed.
