infiltration process in porous preform, such as squeeze casting, vacuum infiltration, variable pressure infiltration and liquid infiltration-extrusion, have attracted research interest due to significantly... liquid and filler particles at room temperature to simulate low-pressure infiltration process of high- temperature aluminum melt in porous media in an organic transparent device. However, the methods......
by reactive gas-pressure infiltration and squeeze casting of Al melt into sintered porous preforms (30% TiO2 and 70% Al2O3 in volume fraction) had an interpenetrating network structure, which attained... is the capillary force. Compared with squeeze casting and gas-pressure infiltration, reactive melt infiltration offers a possibility to produce freeform near-net shape composite at low production costs......
of X10CrNi18-8 steel melt on 30% (mass fraction) Ni-containing alumina based composite ceramic (Ni/Al2O3) at 1 600 °C. The infiltration quality and interfacial bonding behavior were investigated... have been produced by melts infiltration [1–9] and tape casting [10]. In comparison with the tape casting, the melts infiltration is a more economic and attractive method. Due to special requirement......
