“…SiC3D/6061Al exhibits uniform and interconnected structures. The appearance of the phases suggests that the microstructures are in agreement with IPCs SiC/Al described in [1,5,[6][7][8][9]. The continuous 6061Al alloy and the SiC3D skeletons are topologically interconnected in the three-dimensional space, forming an anti-corrosion, anti-oxidation network [13].…”

Interface problems and the destruction of the continuity of the oxide film in the Al matrix usually reduce the corrosion resistance of the material. In this paper, the corrosion resistance of Al matrix composites (AMCs) was improved by introducing the silicon carbide skeletons (SiC3D) obtained with polymer replica technology. SiC3D/6061Al was fabricated by infiltrating molten 6061Al alloy in the oxidized SiC3D using the low-pressure casting method. The corrosion resistance performances of 6061Al and SiC3D/6061Al in NaCl solution were studied by electrochemical, neutral salt spray corrosion (NSS), and salt leaching (SL) tests. Results show corrosion resistance of SiC3D/6061Al is higher than that of 6061Al alloys by open circuit potential (OCP), potentio-dynamic polarization (PDP), and electrochemical impedance spectroscopy (EIS) tests. However, NSS and SL tests show the corrosion resistance of SiC3D/6061Al is lower than that of 6061Al alloy. The reason is a corrosion resistant and anti-oxidation network macrostructure with large interface recombination, few concentrated interfaces, and a small specific area that formed in SiC3D/6061Al. SiC3D cannot damage the continuity of the Al2O3 passivating film, and the network macrostructure greatly improves the corrosion resistance performance.

Aluminum-based silicon carbide (AlSiC) composites with high thermal conductivity were fabricated by post-oxidization of reaction-bonded silicon carbide (RBSiC) preforms in conjunction with vacuum pressure infiltration technology. The study investigated the control of interfacial reactions in conventional sintering and reaction sintering regimes. Conventional sintering introduced a large amount of SiO2, which was detrimental to the thermal conductivity of the AlSiC composite. In contrast, reaction sintering generated β-SiC, which improved the thermal and mechanical properties. An additional post-oxidization process was proposed and applied to the RBSiC preforms to decontaminate the particle interface and prevent the generation of Al4C3. The XRD analysis revealed that the AlSiC composite treated with post-oxidization did not show an Al4C3 signal. Notably, the thermal conductivity of the sample treated with post-oxidization increased by 6.5% compared to the sample that was not treated. The study also analyzed the impact of particle size distribution on volume fraction and thermal properties. The final results showed that the thermal conductivity, coefficient of thermal expansion, bending strength, and bending modulus of AlSiC composites were 237.3 W/m·K, 8.5×10-6/°C, 325 MPa, and 75.9 GPa, respectively.

“…Recent research on metal matrix IPC has been emphasized, with attention being given to the preparation and mechanical properties of ceramic foam reinforced composites at ambient temperature. Xue et al 18 prepared silicon carbide 3D/aluminum composites by using high-pressure nitrogen pressure infiltration. Huang et al 19 investigated the 3D continuous network ceramics in cocontinuous SiC/7075Al composites and found that cocontinuous SiC3D/7075Al composites can prevent three-body wear and have better wear resistance than particle-reinforced 7075Al.…”

The A359-SiCp/Fe interpenetrating phase composites reinforced with three-dimensional network structure iron foam and 20 wt. % SiC particles were fabricated after the infiltration technique by using the newly developed vacuum assisted infiltration procedures. The dry-sliding tribological behavior of A359-SiCp/Fe composites was investigated using the HT-1000 ball-on-disc type high temperature tribometer. The samples were subjected to a variety of temperatures and applied loads to investigate the influence on the wear rate and friction coefficient. In this study, SEM was used to analyses the wear microscopic morphology of A359-SiCp/Fe composites reinforced by iron foam. The wear longitudinal section and the morphology of the wear debris were analyzed by EDS and determined to explore the high-temperature wear mechanism under different temperatures and loads. Hardness analysis from the outer periphery to the core revealed an improvement in hardness. The hardness distribution of the wear longitudinal section is different at different temperatures. The formation of a high-hardness mechanical mixed layer with a different thickness on the wear surface can effectively reduce the wear rate. Microstructural investigations demonstrated that the change in wear debris shape with increasing temperature is mostly related to the change in wear mechanism. Abrasive wear and oxidation wear are the main wear mechanisms. With an increase in temperature and plastic deformation, delamination and adhesion are the predominant wear mechanisms, accompanied by the additional oxidative wear.
