Abstract

The reaction bonding technique offers a promising approach for controlling matrix sintering shrinkage in oxide/oxide ceramic matrix composites (OCMCs), thereby reducing the sintering cracks and enhancing mechanical properties. In this study, aluminum nitride (AlN) was used as an alumina precursor to fabricate OCMCs via reaction bonding. The results indicated that the mechanical properties of the OCMCs could be greatly improved due to the volume expansion induced by AlN oxidation, which reduced sintering cracks, and the high sintering activity of AlN, which enhanced the particle bonding strength in the matrix. However, the strong bonding between the matrix and fibers, attributed to the high sintering activity of AlN, resulted in the decrease of toughness. These findings confirm that the reaction bonding can effectively improve the mechanical properties of OCMCs, but careful control of matrix-fiber bonding is essential to optimize overall performance.

以氮化铝为氧化铝前驱体的氧化物/氧化物陶瓷基复合材料的反应键合

反应键合技术为控制氧化物/氧化物陶瓷基复合材料（OCMCs）的基体烧结收缩率，从而减少烧结裂纹，提高材料的力学性能提供了一种很有前途的方法。本研究以氮化铝（AlN）为氧化铝前驱体，通过反应键合制备ocmc。结果表明：AlN氧化引起的体积膨胀减少了烧结裂纹，AlN的高烧结活性增强了基体中颗粒的结合强度，大大提高了ocmc的力学性能。然而，由于AlN的高烧结活性，基体与纤维之间的强结合导致韧性下降。这些结果证实了反应键合可以有效地改善ocmc的力学性能，但要优化整体性能，必须仔细控制基体-纤维键合。
