| Abstract: | The graded Si3N4/Al composite was prepared by pressureless infiltration process, and theSmacro morphology, the microstructure, theShardness was observed and measured. The effects of technology parameters on pressureless infiltration process were discussed. The result shows that:SN2Sprotective atmosphere,SappropriateSinfiltrationStemperature andSSsuitableSoxidation degree of perform to promoteSaluminum alloySliquidSinto theSSi3N4 matrix. |
