## Description

- description: Al4SiC4 is one of the nanolayered-ternary compounds with excellent
    properties such as oxidation and corrosion resistance at high temperatures, and
    we have paid attention to Al4SiC4 to be applied for ceramic matrix composites
    (CMC) as novel materials for aircraft jet engines instead of SiC. In this study,
    oxidation test of Al4SiC4-based ceramics with SiC fabricated by hot-pressing was
    conducted at 1623K for 12-100 h in air, and their oxidation behavior was investigated.
    After oxidation test, Al4SiC4-based ceramics had oxidation layer with a dual-layered
    structure in 50vol% Al4SiC4/50vol% SiC (Al4SiC4-50), four- and six-layered structure
    in monolithic Al4SiC4 (Al4SiC4-100), and these oxidation layers contained Al2O3,
    SiO2 and mullite. The thickness of the oxidation layer in Al4SiC4-based ceramics
    increased with the oxidation time and the content of Al4SiC4, and obeyed the parabolic
    rate law. The schematic models of oxidation behavior of Al4SiC4-based ceramics
    with SiC were proposed based on the results of the oxidation test. In conclusions,
    the addition of SiC to Al4SiC4 enhanced the formation of mullite, which would
    act as the protective layer, and Al4SiC4-based ceramics with SiC are expected
    to be one of the promising materials instead of SiC.
