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.

“…[2] Besides the raw material combination, also the reinforcement morphology has a major impact on the properties of an MMC. [3] Composites with an advanced, interpenetrating (also bi-or co-continuous) microstructure allows for an enhancement of various properties such as stiffness, [4,5] strength, [6] toughness, [7] wear, [8,9] as well as thermal expansion. [4,10] In particular, the possibility to combine and optimize two or more different features simulataneously, e.g., mechanical strength and thermal expansion or thermal/electrical conductivity, [11,12] thus creating multifunctional materials makes interpenetrating composites stand out compared to classical particle or fiber-reinforced MMCs.…”

Numerical and Experimental Investigation on the Self‐Healing Potential of Interpenetrating Metal–Ceramic Composites

et al. 2023

View full text Add to dashboard Cite

An interpenetrating metal ceramic composite (IMCC) has been investigated regarding the potential as well as the feasibility of self‐healing. Triggered by heating, cracks in the damaged composite located mainly in the Al2O3 ceramic or at the interface could be filled and closed by the liquid AlSi10Mg metal alloy. This healing procedure promises to reduce stress concentrations at crack tips and to improve the mechanical properties compared to the predamaged composite. Two different numerical approaches have been introduced to investigate this assumption and the potential of self‐healed IMCCs for a best case scenario: 1) A simple 2D model to analyze the reduction of stress concentrations in front of a crack tip within the ceramic due to healing and 2) a 3D model based on CT‐scan reconstructed microstructures to study how macroscopic mechanical properties can be restored depending on the amount of predamage. Further, the self‐healing approach has been investigated experimentally for the same composite. Despite the fact that experimental self‐healing of the investigated IMCC is only moderately feasible so far, the study shows the great potential that can still be exploited in order to extend the service life time of IMCC engineering components.

“…Metal matrix IPC research is mainly focused on ceramic-reinforced composites. Fu et al (2021) used pressureless infiltration to fabricate cocontinuous SiC 3D /Al composites with differing porosity per inch (PPI) values and noticed that cocontinuous SiC 3D aluminum composite with 20 PPI has more uniform framework distribution and better wear resistance. Huang et al (2010) prepared cocontinuous SiC 3D / 7075Al composites in which the 3D continuous network ceramics effectively reduce three-body wear that frequently occurs in particle-reinforced composites.…”

“…In comparison with ceramic foam skeleton composites, the cocontinuous metal foam skeleton composites have a unique framework that allows for higher load-carrying capacity, superior thermal conductivity and enhanced wear resistance (Fu et al , 2021). Jiang et al (2015) rolled the two-dimensional titanium mesh and compacted it into a cylindrical 3D porous titanium (p-Ti), and then infiltrated the biodegradable magnesium melt into p-Ti preform with an entangled structure.…”

Purpose To improve the high-temperature wear properties of the SiCp/A359 composite, foamed iron-reinforced SiCp/A359 composite (A359–SiCp/Fe) is prepared. The purpose of this study is to investigate the tribological behavior and mechanism of the A359–SiCp/Fe composites at different temperatures (100–500 °C) and loads (7 N, 10 N and 12 N). Design/methodology/approach The A359–SiCp/Fe composite was fabricated by vacuum-assisted infiltration. The dry sliding tribological behaviors of A359–SiCp/Fe composite were investigated using the ball-on-disc-type tribometer. The worn surface and wear morphology of the longitudinal section were examined using field emission scanning electron microscopy and metallographic microscope. Findings The critical transition temperature for severe wear in A359–SiCp/Fe composite was 50–100 °C higher than in SiCp/A359 composite. Foamed iron prevents exfoliation cracks from penetrating deeper into the matrix. The friction coefficient stability of the A359–SiCp/Fe composite was higher than the unreinforced composite at elevated temperatures. With the increase in temperature, the friction-affected layer was severely worn, and the wear mechanism transferred from abrasion and delamination to oxidation and plastic flow, respectively. Originality/value The preparation procedure for aluminum matrix composites reinforced with foamed metal has been less reported, and the research on the tribological behavior and mechanism of A359–SiCp/Fe composite at various temperatures is insufficient. The foamed iron structure considerably enhances the wear properties of SiCp/A359 composite in elevated temperature conditions.
