| titleOfInvention | A kind of repairing agent and repairing method for surface damage of silicon carbide ceramic matrix composite material |
| abstract | The invention relates to a repairing agent and a repairing method for the surface damage of silicon carbide ceramic matrix composite materials. A reasonable proportion of solid polycarbosilane, xylene, zirconium carbide powder, silicon carbide powder and silicon carbide whiskers forms a moderate viscosity. of liquid substances. The chemical composition of the repairing agent can expressly form a repairing layer with good physical and chemical compatibility with the silicon carbide ceramic matrix composite material in the natural environment. The preparation and construction process of the repairing agent can be operated online at the site of damaged components. After the repairing agent is used to repair the surface damage, a repairing layer with good physical and chemical compatibility with the silicon carbide ceramic matrix composite material body can be formed in the damaged area, and the bonding strength is high and the temperature resistance is high. Reasonable repair process parameters and the combination of solid polycarbosilane, xylene, zirconium carbide powder, silicon carbide powder and silicon carbide whiskers in a reasonable proportion make the service temperature range of the repair layer ‑120 ~ 1400 ℃, and the short-term up to 1650℃. |
