Abstract

In this work, two types self-healing phases, SiBCN and SiB₆, with low complex permittivity were introduced into SiC_f/Si₃N₄ composite to improve the oxidation resistance. The oxidation behavior of composites depends on the cracking degree and crack-healing ability of the matrix. With the incorporation of SiBCN and SiB₆, a large amount of glass phase can be generated, and the cracks can be better filled even the serious matrix crack. After the oxidation of 1200 ℃, the residual strength of SiC_f/Si₃N₄ composite incorporating SiBCN and SiB₆ can reach 227 MPa, while that of SiC_f/Si₃N₄ was as low as 120 MPa.
