目前的工作涉及 SiC 的气压渗透 - 具有选定孔隙率的铝合金预成型件，以便制造具有比 SiC 块体材料更高的延展性以及比铝块体材料更高的温度和抗蠕变性的互穿复合材料。对制造的复合材料的质量进行金相分析，证明复合材料具有良好的渗透性。残余孔隙率也被确定，并且可归因于闭孔率和开孔率的渗透不足。可以看出，与未增强的基体材料相比，预成型件的渗透导致抗压强度增加，并具有合理的延展性。
The current work deals with the gas pressure infiltration of SiC - preforms of selected porosities with an aluminum alloy in order to manufacture an interpenetrating composite with higher ductility in comparison to SiC bulk material and a higher temperature and creep resistance in comparison to aluminum bulk materials. The quality of the manufactured composite is analyzed metallographically which attests a good infiltration of the composite. The residual porosity is also determined and can be attributed to the closed porosity and insufficient infiltration of open porosity. It can be shown that the infiltration of the preform leads to an increase in compressive strength with reasonable ductility in comparison to the unreinforced matrix material.
