AI Technical Summary
Existing high-temperature resistant coatings have difficulty forming a continuous and dense porcelain layer under high-temperature conditions, resulting in poor substrate protection and insufficient interfacial bonding, which easily leads to cracks and peeling, affecting protective performance.
A core-shell polyborosiloxane resin liquid and a reaction shell microsphere are synergistically designed. By constructing a core-shell microsphere coating system, a continuous and dense protective layer is gradually formed during heat treatment. This includes the preparation of the core-shell polyborosiloxane resin liquid, the preparation of ZrB2/SiC composite particles, and the construction of the reaction shell, forming a multi-layered protective structure.
It improves the coating's oxidation resistance, ablation resistance, thermal shock resistance, and adhesion stability, extending its service life and providing effective long-term service reliability.
