- •
Glass phase has a great influence on structure and properties of MoSi2-BAS coating.
- •
The liquid glass phase content was controlled by the addition amount of B2O3.
- •
Porosity of coating decreases and coating becomes denser as B2O3 content increases.
- •
The coatings with 2 wt%–4 wt% B2O3 content form a desired gradient structure.
- •
Gradient coating exhibits excellent bonding strength and thermal shock resistance.
