WebMay 18, 2024 · Here, C f /SiC–ZrC–ZrB 2 composite was fabricated by reactive infiltration of ZrSi 2 melt into sol-gel prepared C f /B 4 C–C preform. (PyC–SiC) 2 interphase was deposited on the fiber to investigate the degradation mechanism under ZrSi 2 melt. It was revealed that the degraded interphase exhibited typical features of Zr aggregation and ... WebA W/ZrC/SiC multilayer coating is prepared on carbon/carbon (C/C) composites by reactive melt infiltration (RMI) and atmospheric plasma spray (APS). The morphology and microstructure of the coating are characterized by scanning electron microscopy coupled with energy dispersive spectrometry (SEM-EDS), X-ray diffraction (XRD), and focused ion ... WebFeb 25, 2024 · A two-step method combining reactive melt infiltration and slurry coating was employed to fabricate completely protected C/C composites.
