Thus, functional gradient material (FGM) should be a feasible route to introduce Ln2Zr2O7 as oxygen insulation to ZrB2 based materials.
The XRD patterns of the ZrB2/SiC-Sm2Zr2O7 materials were shown in figure 3.
From the results it can be seen that no significant phase transformation was found in the materials.
Minute ZrSiO4 (31.8°) was detected in the materials with high ZrB2/SiC content, which caused by the solid solution of ZrO2 and SiO2 from the row materials.
