文摘
- •
ZrB2–SiO2 coating was prepared by infiltrating silica sol into porous ZrB2 layer.
- •
Dispersed ZrB2 particles improved the oxidation resistance of the coating.
- •
Formation of ZrO2 and ZrSiO4 generated compressive stress during oxidation.
- •
Compressive stresses restrained the formation of cracks in the coating.
